Hi Stryd_one, Thanks. Using all four IO's is no issue. These IOs are available through the expansion slots we're using for the Miss Parker+ daughterboard; we're actually using a stereo input and output pair for that AL3201 extension. What needs to be done is duplicating the actual IO part three times on the free IOs. Concerning the LCD, it may be a bit more complex. With the EZ-USB part we've chosen, we're a bit short in output lines. We're actually using the data port as extension and latching it and triggering it with the external write. You can of course use the same principle but I don't know if that will be Ok to drive the LCD. On the other hand, I guess an easy fall-back solution could be to use some I2C expansion chip. We're bringing the I2C lines to the expansion slots along with the data port of course... All in all I think it's feasible, maybe a bit tricky to some extent but feasible. Best regards, Lall

Hi all, Actually, you need that AL3201 + a AL1101 and a AL1201 for digital/analog conversion + a few extra chips around for the analog input/output stage, reset circuit and power supply of course. You can find what you need in the following document: http://www.wavefrontsemi.com/UserFiles/File/AL_Info/AL32/WavefrontEV3201A.pdf. You can ommit the micro-controller from that document if you want to use only the presets. That's actually the very good point about that chip if you're ready to live only with presets. You don't need any modification in the SID application, you simply need a 16 position rotary switch to control the presets and that's all. OK, then the effect is not linked with the SID preset, ... but that's already a first interesting step I believe and it definitely adds some space to the sound. Best regards, Lall

Hi SysEx, The Wavefront AL3201 is such a chip. This is a pretty nice one as it contains 16 presets (several reverbs, chorus, flanger, ...) but can also be programmed. So you can start easy by simply using the presets and then expand the system later on with user-defined effects. You can find information on that chip from the products section of Wavefront's website: http://www.wavefrontsemi.com/. You can use the AL1101 and AL1201 for A/D & D/A conversion. We're using this chip in our project along with the AL3101 which is better at filteing & compression tasks but has too few memory to be able to perform chorus and reverb. You can find some demo tracks (including a mono SID + AL3201 & mono SID + AL3101 + AL3201) from there: http://www.axoris.be/MissParkerPlus.php. I thought already a few times of doing an extension board to be connected to a Core containing such an AL3201 and/or AL3101 but never even started on that due to a lack of time. Best regards, Lall

Hi all, Xanboroon and I are pretty interested in such a bulk order. Up to now, we've been too lazy to try to find old SB cards I must say... We are looking for 2x YMF262-M and 4x YAC512 in total. Best regards, Lall

Salut a tous, Ca y est, les listes de composants necessaires "BOM" pour une Miss Parker Plus sont dispo sur le site a la page suivante: http://www.axoris.be/MissParkerDetails.php. En ce qui concerne les chips, on les achete chez Profusionplc et c'est effectivement cher. Heureusement, il en faut pas beaucoup ;) Par contre, ce qui est pas mal c'est que pour une certaine somme, on ne paye pas les frais de port... A+ Lall

Salut Fabricio, Je m'occupe pas de la partie hardware en fait. Je pense que cette liste doit pas etre mega compliquee a generer si ce n'est deja fait, je vais demander au pote qui s'occupe du HW et je la mettrai sur le site aussitot... A+ Lall

Waouw that rocks! I'd really like to build such a board. That's exactly what I was aiming for :) Just one minor question, is that possible to run the mixer with +/- 9V instead of 12? I'm asking because I only have 8580 and that would make the power supply easier if I would just have +5, +9 and -9V. Best regards, Lall

Hi Davo, Very interesting!!! I was thinking of doing such a thing myself but I can't find any time for doing so. I can't find time either to put my mono-SID in a box (http://www.midibox.org/forum/index.php?topic=2736.msg17936#msg17936) I could be interested into trying this out. What kind of size is the board? I'm limited to 300x200 mm but I guess it should be smaller anyway. Is it possible to take a look at the layout of the PCB via some image/pdf/whatever? Best regards, Lall

Salut Goule, Oops, je pense que j'ai lu un peu trop vite. :-[ Enfin, heureusement la reponse reste la meme, ca fonctionnera pile-poil. A+ Lall

Hi, That really looks nice. I like a lot the idea of handling everything from Cubase and especially automating parameter changes from Cubase... I'll give it a try soon ;D Kind regards, Lall

Salut Goule, Ouais c'est exact, pas besoin de module en plus, le SEQ fait tout tout seul... A+ Lall

Hi Freecomm, Indeed, by modifying the firmware running on the EZ-USB, you can certainly make it a wav reader/player. I'm using the very same chip as a HID device, the black magic to change skin is mainly in the descriptors. There are however two things you need to consider: 1) you need to get the samples in/out and therefore you need a DAC/ADC that can interface in a nice way with the EZ-USB. You should look at how they are implementing what they call Fast transfer mode or something of that kind; it's actually a kind of FIFO that can help you speed up considerably the transfer duration. 2) you need to get a firmware up and running with audio class functionality. I've quickly looked at the spec from the USB site some time ago and that's quite indigestible. Finding a good sample on the web would be very much appreciated I presume. If someone knows about one, I'm interested as well ;) Best regards, Lall

Hi all, I've come across this topic on the wxWidget forum: http://www.solidsteel.nl/users/wxwidgets/viewtopic.php?t=797. I know nothing about phpBB but thought it may be a point of attention for this forum as well... Best regards, Lall

Salut, Pour notre Miss Parker (http://www.axoris.be/MissParker/pics/MissParker3.jpg), on utilise la reference suivante: MP0037/2 de Bulgin ( Réf Farnell : 311-4648 ) Le seul probleme de ce bouton est qu'il coute ~11 euros hors TVA :( Par contre, il est clairement "vandal resistant" ;D On est en train de se demander si on ne passerait pas a un autre bouton en plastique +/- 10 fois moins cher mais faut voir si ca tient aussi bien... A+ Lall

Hi, It actually means that one output can drive up to 20 inputs. So you could expand the copy module to have 20 outputs (IC1B->IC1E) out from the single IC1A inverter. With more, you may enter into some problems... Best regards, Lall

Actually, the board is equipped with connector giving access to the other IOs of the chip so with a "small" extra board, you could add AD/DA to have four stereo channels in total. The AL3101 is actually able to manage up to 8 mono channels. We use 2 for our standard stereo IO and 2 others for connecting the AL3201. There has been a post on this forum with the PCB of a board with Alesis DAC or ADC (I don't remember) as the one we're using. I think these PCBs could be reused to extend the IO capabilities... I think that adding more channels would require no modification in the firmware, you would only have to create DSP application using all your input channels... It is unfortunately up to date. As I had no external pressure on that one and no real need personlly, I mainly concentrated on the PC software side lately. Moreover, I have some program size issues so I will need to optimize some parts if I want to add MIDI unless I kick out the USB support of course ;). But adding MIDI is still in the plan. It would be a very nice "tool" to trigger ADSRs, ... and why not making synthesis ;D Best regards, Lall

Hi all, Indeed, the Miss Parker and certainly the Miss Parker Plus can help in here :) On our website, we have some demo files available of a mono-SID post-processed with the beast. Here is what the AL3201 can do alone with Chorus/Room1: dry - http://www.axoris.be/MissParkerPlus/demo/Chorus_Room1-SID-off.mp3 wet - http://www.axoris.be/MissParkerPlus/demo/Chorus_Room1-SID-on.mp3 Here is what the AL3101+AL3201 combination can do: Phaser on the AL3101 and Hall2 on the AL3201: dry - http://www.axoris.be/MissParkerPlus/demo/Phaser_Hall2-SID-off.mp3 wet - http://www.axoris.be/MissParkerPlus/demo/Phaser_Hall2-SID-on.mp3 Phaser on the AL3101 and Plate1 on the AL3201: dry - http://www.axoris.be/MissParkerPlus/demo/Phaser_Plate1-SID-off.mp3 wet - http://www.axoris.be/MissParkerPlus/demo/Phaser_Plate1-SID-on.mp3 Some other demo files but not on a SID can be found from: http://www.axoris.be/MissParkerPlus.htm and http://www.axoris.be/Effect_Resources.htm The AL3101 is actually very much suited for EQ-like filtering, compression, distortion, ... while the AL3201 is more suited for reverb, chorus, ... The combination of both is actually quite interesting. I think it could be feasible to control these DSP from a PIC even though we've chosen for the EZ-USB in Miss Parker. The Miss Parker manager is able to cope with any HW device as communication is made through libraries loaded at run-time so the whole tool suite related to Miss Parker could be reused normally... Voila, voila, have fun with the demos ;) Best regards, Lall

Hi Torsten, Thanks for your answer, it is actually very good news for us. Hi Smash and Rowan, Thanks a lot for nice messages about the club. I'm also part of that club for some years and it's nice to feel a little bit less alone  ;) Best regards, Lall

Dear all, I have a pretty stupid question for which I think I know the answer but I'd like a double check... Is it possible to completely re-allocate every single IO of the SEQ application? From what I've seen in the ...setup.asm file, I think so but I'm wondering if there's anything used in DIN/DOUT that is fixed and that can't be changed? For the history and for a laugh, the thing is that Xanboroon and I are making together two sequencers and later two sids. We've decided to go for a home-made front-panel PCB to ease the soldering and connection. Unfortunately, there was no text on the printout, the mirror didn't work so the print was on the wrong side; that was much more than enough for me to etch the PCBs in wrong way :-[ The pity is that the PCBs were really good, euh well except for the "small" mistake ;) so we're now looking at ways to still use them by re-allocating everything in the "opposite" order... Thanks in advance, Best regards, Lall

Hi, I've had the same problem during the debugging phase of my mono-SID. I unfortunately don't remember for sure what was the cause but I think it was due to a short on some lines of the DIN that was connected to my Core or more precisely some of the interface lines between the DIN and the Core. Good luck... Lall

Salut a tous, Ceci est une traduction du post suivant: http://www.midibox.org/cgi-bin/yabb/YaBB.cgi?board=concepts;action=display;num=1091483193. J'ai passé les dernières semaines a bosser sur l'AL3201 de chez Alesis. C'est un DSP spécialisé dans les effets de reverb, chorus, ... Il est super intéressant pour notre Miss Parker qui contient pour sa part un AL3101. L'AL3101 est limité en mémoire et ne permet pas de faire de la reverb d'où l'intérêt d'ajouter un AL3201... Pour l'instant, l'AL3101 et l'AL3201 tournent ensembles et j'ai enregistré quelques samples de mon SID avec des combinaisons d'effets. A mon sens, c'est une solution assez intéressante pour ajouter de l'effet sur un SID. La page Web explique comment le tout est connecté. J'ai pas fait de carte stand-alone mais je pense que ca devrait pas etre trop compliqué de mettre un AD/DA, AL3101 et AL3201 sur une petite carte DIY. Si on veut pas contrôler les effets, une eeprom pour stocker le code de l'AL3101 suffira, sinon un micro-controleur sera necessaire. Enfin, voila voila, les samples sont dispo ici: http://www.axoris.be/MissParkerPlus.htm A+ Lall

Hi all, I've been busy these last weeks with the AL3201 chip from Alesis (now Wavefront semiconductors). This chip which can handle reverb, chorus and the likes is a perfect companion to the AL3101 of our Miss Parker project. I'm at a point where the AL3101 and AL3201 run together and I've processed some SID sounds with this chip combination. I think it's a quite nice solution for digital effectorization of the SID... You can find from the Web page how the whole thing is connected together. Even though I haven't done that, I'm pretty sure one could make quite easily a DIY board containing the AD/DA, AL3101 and AL3201 chips. If you want elaborate control over the effects, a micro will be required otherwise simple EEPROM connected to the AL3101 containing pre-defined effects and the pre-defined effects of the AL3201 can make the job... The sound samples are available from this page: http://www.axoris.be/MissParkerPlus.htm. Best regards, Lall

Salut Pilo, Ouaip, on peut faire un EQ avec sans aucun probleme. Le module n'est pas encore dispo pour Agalag (notre application generator) mais c'est une question de faineantise plus qu'autre chose. En ce qui concerne le compresseur, on a deja tout le code dispo pour faire une appli. A vrai dire l'appli est prete mais pas encore le projet pour Miss Parker, voila pourquoi c'est pas encore en ligne. Sinon, cette appli sera equivalente au CLX-440 de chez Alesis mais en stereo donc plutot la grosse artillerie: compresseur/limiteur/expander, soft/hard knee, RMS/peak, ducking/keeying, look-ahead delay ... Question simulateur, il est deja "multi-plateforme"-friendly dans le sens ou il compile et tourne sous Linux. Le streaming est fait avec PortAudio et a ete teste sous Linux avec OSS je pense. C'est Gregor (gregor@axoris.be) qui s'occupe de la partie Linux donc les questions la-dessus peuvent lui etre envoyees. Ceci dit, je pense bien que PortAudio (http://www.portaudio.com) supporte Jack donc il sufferait en principe de re-compiler. Pour la table de mix, ca serait pas mal interessant effectivement. Pour ma part, je preferais l'interieur en numerique et l'exterieur en analogique car j'ai rien en digital dans mon installation. Enfin, ca revient a remplacer le bloc d'IO par un autre... ;) Pour le SHARC, ouaip on a laisse tombe l'idee. En fait, l'appareil qu'on voulait construire a la base et qui aurait utilise un SHARC (ou Motorola ou TI d'ailleurs) revient a un Chameleon et vu le peu de temps qu'on arrive a passer sur ces projets, on saurait pas faire mieux que Soundart donc voila on a laisse tomber... Par contre, en ajoutant un AL3201 a l'AL3101, on arrive a une combinaison plutot sympa et facile a mettre en oeuvre donc on va attaquer cette voie la. A+ Lall
