Just answered to the same issue in the german section: I installed MacOS 10.6 meanwhile, therefore I'm not able to check this (mmj doesn't work under Snow Leopard anymore). Either it's sufficient to activate the 32bit version of Java with the Programs->Utilities->Java Preferences app, or you have to install Mandolane (unfortunately the mmj guys discontinued the development) Best Regards, Thorsten.

Mit einem selbstprogrammierten Meta Event waere das schon ohne grossen Aufwand moeglich, doch es stellt sich die Frage, ob es nicht besser waere, die Motorfader-Positionen (sowie LEDs) aus der Software heraus zu kontrollieren, so dass die Informationen bspw. beim Wechseln eines Songs/der Session nicht durcheinander kommen. Welche Software verwendest Du genau? Gruss, Thorsten.

Ich befuerchte, dass Du mit dem Java Update nun genau das gleiche Problem wie alle MacOS 10.6 User hast. Die Jungs von mmj haben den Support leider aufgegeben, so dass Du nun stattdessen den Mandolane Treiber installieren musst (die Lizenzgebuehr ist akzeptabel) Doch es gibt noch Hoffnung: starte mal Programme->Dienstprogramme->Java Einstellungen, und deaktiviere die 64bit Java Option. Gruss, Thorsten.

It is possible to support 64 additional button/LEDs assigned to static MIDI events by adding some code, but for your usecase the application proposed by Nasrudin is much better - it's small and easier to customize (if really required). Best Regards, Thorsten.

Yes, Wilba works on the PCB. :) I remember that you wrote me a PM concerning these buttons a while ago. However, they are far too expensive for such a project. You are free to use these buttons though, but I'm not sure if it will be possible to support them by a standard PCB, as the additional drill holes would increase the costs for everybody. You would have to layout your own PCB. Nice idea, using SMD wouldn't hurt here (contrariwise, it would be easier to solder them at the top of the PCB). But they would also increase the distance to the knobs, accordingly the view angle gets wider, and this increases the danger that the LED light of a certain knob is visible on other knobs as well. Therefore common 3 or 5 mm LEDs would be better. Thanks for the link! The silicon material which was proposed by Per is *much* better than a latex glove or those balloons. Especially the ones with 2mm thickness. It's for example available here: http://www.modulor.de/shop/oxid.php/sid/x/shp/oxbaseshop/cl/details/cnid/AAT/anid/AATD I purchased the 2,0 x 240 x 500 variant for 9.90 EUR and it will be sufficient for the complete 16x16 BLM + some control buttons/LEDs. Of course, you have to take care that the buttons are not too close together - it worked at my side with the distance you can see on the pictures above. Best Regards, Thorsten.

Konfortabler geht es unter Windows mit MIDItrix: http://www.hermannseib.com/miditrix.htm Gruss, Thorsten.

Hallo, einem Freund ist neulich etwas aehnliches passiert... Ist der mittlere Pin des kombinierten MIDI Steckers mit Masse verbunden? Dann waere dies ein Designfehler im Gitarrenverstaerker, und es ist nicht auszuschliessen, dass durch eine Masseschleife zwischen dem MB64 Netzteil->Core MIDI Out->Verstaerker->Steckdose->MB64 Netzteil und der daraus resultierenden Ueberspannung (mindestens) der PIC geschrottet wurde. :-/ Um dem in Zukunft vorzubeugen, hilft nur ein spezielles (selbstgemachtes) MIDI Kabel, bei dem die Masse auf einer Seite *nicht* angeschlossen ist. Gruss, Thorsten.

RC34 has been released - ChangeLog: o fixed race condition in SusKey portamento function o Note Off keys which are not in the note stack are ignored now o implemented CC#123 (All Notes Off) Complies to MIDI spec. Means: only CC#123=0 will unplay all notes, all other values (1..127) are silently ignored o new wavetable control function "Key" allows to select a wavetable step with the currently played note inside the given Begin/End range. E.g., with Begin=0x00, End=0x7f, KEY=on, Par=200 you are able to define different ENV1 Decay parameters for each note. There are much more usecases of course (e.g. different LFO values, different waveforms, Sync/Ring enable/disable in certain keyranges) - be creative :) o Arpeggiator "Easy Chord" function now active in default Lead/Bassline/Multi patch o sammichSID: F2 button now jumps to Knob page by default (especially nice for bassline patches, for other engines the knob assignments are mostly not preconfigured) o Multi Engine: Knob parameter #6 and #7 now allow to control CutOff frequency of left/right channel SID separately. Note that this isn't consistent to Lead/Bassline assignments, but unfortunately there is no other possible solution. o filter page now allows direct L/R channel selection o the full control surface now handles the first press of Osc Select, Env Select, LFO Select and Filter Mode/Channel Select as a "jump to page" function if that page was not displayed, and thereafter, function as a "change selection" function. Thus if you are not on the LFO page, pressing LFO Select jumps to LFO page, and then pressing it again will change the selected LFO. o this is the christmas edition, therefore the Matrix LEDs are flickering during startup ;-) [/xml] Best Regards, Thorsten.

There are several ways to do that. All are using a CC track and modulate the length in Layer C. Start with track length of 4 steps You could gate the sound with the CC#7 (Volume) controller. Advantage: will work on any synth, disadvantage: current volume setting will be overwritten. Therefore I usually prefer to sequence CC#11 (Expression) instead, which should have the same effect. Advantage: it doesn't touch the general volume setting, disadvantage: not supported by all synths, especially not by VST/virtual synths Another good method is to gate the filter cutoff. The CC number depends on your synth. Best Regards, Thorsten.

That'ss indeed an unexpected error mode! I'm glad that you got this fixed :) Best Regards, Thorsten.

No, ribbon cables are not included. Best Regards, Thorsten.

What happens if you pull IC1 of the DINX4 module out of the socket, and connect pin 9 (QH pin) directly to ground (Vs) or +5V (Vd) I would expect 128 "on" events if connected to ground, and 128 "off" events if connected to 5V without retriggers. Can you confirm this? Please use MIDIO128 for testing, as on the MB64 firmware this experiment could cause unintended menu operations (like a snapshot) Best Regards, Thorsten.

Sounds like a cold/loose connection/insulate contact/slack joint or however you call it... ;) Did you already resolder the pins around the affected SID/74HC595s and PIC? Best Regards, Thorsten.

What do you guys think about following inexpensive solution for a giant 16x16 Duo-LED Button matrix? :) I got this inspiration from the Flame Six-in-a-Row project, the creator Per Salzwedel was very helpful and gave me the construction details. Self-adhesive "3M elastic buffers" (rubber feets) are used as button caps. Costs: ca. 0.06 EUR pp. if we organize a bulk order. Buttons are "TASTER 3301", available at Reichelt for 0.11 EUR pp. Single-color LEDs are "SLK 5MM RT", available at Reichelt for 0.07 EUR pp. For Duo-color (red/green) "LED 5 RG-3" could be used (0.15 EUR pp.), but this one has only a diffuse cap. Does anybody know where to get them with transparent cap? In addition - and this is the trick! - some kind of transparent silicon mat (german: "transluzente Silikonplatte") is required (2x240x500 mm for ca. 7 EUR) to give a perfect tactile feel like if the button would be directly under the cap. So, estimated costs (w/o PCBs and Case/Frontpanel) for a 4x16 BLM: ca. 20 EUR, 8x16 BLM: 40 EUR, 16x16 BLM: 80 EUR Best Regards, Thorsten.

Hi, do you mean digital gate outputs, e.g. to trigger percusive sounds? 8 gates are available at J5, and up to 64 gates can be added by using two DOUTX4 modules. The upcoming BLM_SCALAR (hardware) will give you a nice user interface :) Here a snapshot of the SW based emulation: Best Regards, Thorsten.

Hm... nobody reported such an issue before. Wrong MIDI values normally indicate a baudrate mismatch, e.g. because the wrong crystal is used (GM5 requires 16 MHz). But this would also lead to wrongly received MIDI events, and the correct events would be received on a direct MIDI OUT->IN loopback. So, the only explanation I have (yet) is, that you are using the wrong resistor value for R38 and/or R50. Both should be 220 Ohm. A higher value would lead to unstable transfers. In your examples more 1s are received than 0s, which confirms my hypothesis (1 is the idle state) If this isn't the reason, please try following experiment: put at jumper at J6:I1 and J6:O1 to short the In/Out connection (don't worry, this won't lead to damages) - is the loopback working now? Best Regards, Thorsten.

Hi, see the mios32_config.h file of this tutorial application: http://svnmios.midibox.org/filedetails.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Ftutorials%2F012_ain_muxed%2Fmios32_config.h The three AIN multiplexer selection lines can be mapped to any free IO pin. In this example I used some J5C pins, but you could also use J19 pins if they are free - this would allow you to use J5C for 32 additional pots/faders. Best Regards, Thorsten.

The reason why you took two cores was, that only 64 multiplexed AIN inputs are supported by MIOS8. This limitation doesn't exist for MIOS32 anymore. Three AIN modules can be connected to J5A/B/C, and the three AIN multiplexer select lines have to be mapped to free IO pins (e.g. J19) Best Regards, Thorsten.

Here a closer lookup - due to the imperfections (see LEDs) this one isn't qualified for the MIDIbox of the Week section ;) The engravings are painted with "Revell Email Color" (this is neither an acryl color, nor a new web 2.0 invention - email means translated "enamel"), available for 2 EUR in toy/modelbuilding departments of bigger supermarkets (at least in germany). During the session yesterday I noticed three bugs in the Multi Engine which I would like to fix before the next release. Best Regards, Thorsten.

Successfully built my sammichSID - thanks Wilba! This video is for you! :) Best Regards, Thorsten.

I'm unable to reproduce this. Could you please give me step-by-step instructions? Please try it with the default lead patch first (press SHIFT+GP2 (E.) multiple times until "Ld" appears) If the issue cannot be reproduced with this patch, please send me your patch for further analysis. Best Regards, Thorsten.

I never got a LPT based wiggler working on my PC, I tried it with the internal LPT port, and with an extension card. The UART based bootloader worked w/o issues through a USB COM interface. Best Regards, Thorsten.

Hallo, ja, in einem BankStick kannst Du 32 separate Baenke speichern. Allerdings werden nur 8 Motorfader supported - mehr ist mit dem PIC nicht moeglich. Gruss, Thorsten.
