Jaicen Posted May 19, 2006 Author Report Share Posted May 19, 2006 Looking good guys! I'm still working hard at these modules, i'm just having a few difficulties with the DR-110 snare noise portion. I think I've resolved the problem, I just need to check it (later today hopefully). Layouts for the instruments are done, except the digital noise/chime section for the hats. I'm also cloning a complete DR-55, not just the kick & rim, as i've just found the trigger points in my TR-505. I've always wanted a 55, so i'm building these four voices into a standalone box triggered from the 505. I notice the info is still to be entered into the Wiki, but the trigger points are as follows:R80 - KickR75 - SnareR2 - Clap/RimR69 - CowbellR68 - CongaR63 - HatsR62 - Ride/CrashR60 - TomsEDIT: DR-110 is working as per the layout. The noise source I was using was too quiet so I tried it with the digital noise from my real DR-110 and it worked fine. Quote Link to comment Share on other sites More sharing options...
DrBunsen Posted May 19, 2006 Report Share Posted May 19, 2006 One of the guys in the music collective/label thing I work with occasionally has piped up about modding a preset boom-cha rhythm box of his, an ARISTA SM200 Turns out it's the same as one of mine, which I've been meaning to mod for ages, so we're going to get stuck in to it. I've added a link to the schematic to the wikipage. It's got a nice kick, a bloopy sort of tom/clave sound, and a noise snare.Oh and stryd.....Rockby are selling them for $20 - 6 left.

Jaicen Posted May 19, 2006 Author Report Share Posted May 19, 2006 Looks like a good deal to me! Shame it's not in the UK, I think shipping would be overly expensive. how many sounds does it have??EDIT: I finished the layout for the DR-55 voice board tonight. It includes all four voices on a 4.9x2.2" board, but does not include the noise generator or accent/output buffers yet. I'm aiming to fit it all into a 5.5 x 3.5" board to fit in my chosen enclosure, so it's looking good. Quote Link to comment Share on other sites More sharing options...
stryd_one Posted May 20, 2006 Report Share Posted May 20, 2006 Heh I remember ClanAnalog parties in Sydney maaaany years ago :)There's another $20 that stores gonna take from me ;) Quote Link to comment Share on other sites More sharing options...
DrBunsen Posted May 20, 2006 Report Share Posted May 20, 2006 how many sounds does it have??Four. And it's about the same size as your finished board too :) Quote Link to comment Share on other sites More sharing options...
slcrz Posted May 22, 2006 Report Share Posted May 22, 2006 Hey everyone,Trying to catch up with these projectsI have a few question:I 'm planning to do Hallucinogen 808 clone Voices and (maybe some 9090 voices as well)in the same box with an integrated MBSEQ1. using DOUTx4 to trigger voices do I need another DOUTx4 module to trigger leds at the same time ?2. Is MBSeq respond to outside midi message from Soft sequencer for example to trigger play patterns ? (if yes I don't need to implant simple midi to my box)3. How do u manage the PSU for voices AND PSU for core module in the same box ?4. Can MIOS be programmed to do the job :) ?Sorry for all the question a onceTx & lets keep up the good work !

illogik Posted May 22, 2006 Report Share Posted May 22, 2006 hi1. using DOUTx4 to trigger voices do I need another DOUTx4 module to trigger leds at the same time ?you can make a a small circuit (led+transistor? check cgs.synth.net for "led driver") which you can connect directly to the triggers, but maybe there an easier way?2. Is MBSeq respond to outside midi message from Soft sequencer for example to trigger play patterns ? (if yes I don't need to implant simple midi to my box)i don't understand you completly; but mbseq can be controlled by midi; the specs are on the mbseq pagesalso keep in mind hallucinogen's design also uses another core+doutx4 module running MIDIO128 for triggering the drumvoices. if you want to keep it minimal you could skip the whole mbseq and play the modules with your soft seq (but then you won't have accent (signal from mbseq cv out))3. How do u manage the PSU for voices AND PSU for core module in the same box ?there is a design on hallucinogens sitecheers, marcel Quote Link to comment Share on other sites More sharing options...
slcrz Posted May 24, 2006 Report Share Posted May 24, 2006 Thank you very much, things are getting clearer...The psu design on hallucinogen site is dead,maybe ill try to reach him to get the schematics.Tx again Quote Link to comment Share on other sites More sharing options...
slcrz Posted May 30, 2006 Report Share Posted May 30, 2006 Hi,I sent a mail to hallucinogen about the PSU design and partlistbut i'm not sur i'm gonna get an answer...Does anybody here have the schematics/pcb/partlist for this babyand would be willing to share.TX Quote Link to comment Share on other sites More sharing options...
stryd_one Posted May 30, 2006 Report Share Posted May 30, 2006 Argh! I hate when DIY projects turn vaporware and the names disappear and stop returning emails :( It's such a wasteful loss not to hand the project over to someone else....Ah well.....

Jaicen Posted May 30, 2006 Author Report Share Posted May 30, 2006 I hope that wasn't a hint Stryd ;)Be patient. I spoke to Hallucinogen a while ago, he took a few weeks to get back to me I think. I think the PSU link was working, i'm sure I've seen it. It's really not a big deal. If you can build the modules, the PSU should be no sweat!

illogik Posted May 30, 2006 Report Share Posted May 30, 2006 yeah people, have some more patience; some people have other things to do in the real world ;) btw hallucinogen is very helpfulslcrz; there are examples here too for instance the opl3 psu >>can be modified to give bipolar 15 volt instead of 12; northernlightx was designing a psu aswell.off you go... ;D Quote Link to comment Share on other sites More sharing options...
stryd_one Posted May 30, 2006 Report Share Posted May 30, 2006 I hope that wasn't a hint Stryd ;)Be patient.Nah no hint, just a big pet-hate of mine :-\My apologies, I must have mis-read the date on the previous post, I thought it'd been a couple of months since slcrz sent the first email... I didn't mean to seem impatient, I just screwed up :( sorry!But yeh, it's only been a week slcrz, you're not waiting long enough. Quote Link to comment Share on other sites More sharing options...
slcrz Posted May 31, 2006 Report Share Posted May 31, 2006 tx for the support answers...I'm going to be patient ... anyway it's not like i'm in a rush or something :)i'll focus on my HH section I'm a real novice in DIY andI was just a bit scared of not being able to complete this project,but I see that there are cool people willing to help,so Im going to take it slow.thanks again.

DrBunsen Posted June 15, 2006 Report Share Posted June 15, 2006 Added Boss PC-2 schematic and noise gen mod to the drum wiki/edit/ added a whole bunch of other stuff besides. Come on guys pitch in! Quote Link to comment Share on other sites More sharing options...
Jaicen Posted June 15, 2006 Author Report Share Posted June 15, 2006 Good stuff Doc! I've got a PC2 clone myself actually (an AMDEK PCK-100) which I usually trigger from the accent out on my DR-110. Can't say I use it all that much myself, but it's a nice circuit to have if you're building a set of analogue drums for sure. Is that noise generator mod intended to be added to the PC-2?? Looks like it is from the schematics, I wonder what that sounds like. I imagine you could get some nice snare sounds if you filtered the noise as well.

stryd_one Posted June 16, 2006 Report Share Posted June 16, 2006 Sorry I'm not getting in there yet doc... I'm kinda flat out right now, I think I'd be more of a hindrance than a help :( But thanks heaps, the drumstuff page is looking fan-freakin-tastic!!!At the very least, I promise to make you some of the best drum synth patches you ever heard, once it's all done :) Quote Link to comment Share on other sites More sharing options...
DrBunsen Posted June 20, 2006 Report Share Posted June 20, 2006 Roland TR-77 on ebay.au $49.95 finishes in under two days. If it wasn't interstate (NSW) I'd probably grab it myself.Bueller ... Bueller ... Quote Link to comment Share on other sites More sharing options...
moogah Posted June 21, 2006 Report Share Posted June 21, 2006 WOA... What the hell took me so long to show up in this thread?RE: Hallucinogen's 808 clone: the PSU schematic is MIA and Sebastian didn't have them available when I asked months ago. I've actually got a set of his boards all etched, stuffed and wired on my bench now. It really does sound like the original, kick drum in particular. Now, as for his clone becoming "vaporware" I would agree that Sebastian seems very busy with other endeavors (when was the last time he posted here?). The good news is that I took it onto myself to continue work on the project, specificaly creating a layout in eagle that combines the 808 analog section with a MBSEQ with all the proper modifications to work like the 808. ETA about 2 weeks and I will be gearing up to do a run of boards. I've also been working on my 9090 PCB's I got from Trevor this winter. Good stuff there.I will also then have layouts for all the instruments in eagle format, most of which will fit in the 100x80mm size of the free program if you all would like to tweak them ;) Quote Link to comment Share on other sites More sharing options...
Jaicen Posted June 29, 2006 Author Report Share Posted June 29, 2006 Hmm, tough act to follow there Moogah! How about this then?? I've got all the voices from the DR-55 & DR-110 cloned now almost ready for prototyping. I still need to add the noise generators and voltage regulator to the main PCB, but it's almost there! You can check a component overlay here: (Measures approx 6x5" which is not bad!)If it looks strange, its because I did the layouts in a modular fashion then stitched them together as it were. I'll give you all an update when it's done. I have to open up my DR-110 first to check the schematic, as I suspect that there's some filtering missing from the snare noise source. Anyway, what do you guys think?? Quote Link to comment Share on other sites More sharing options...
moogah Posted June 29, 2006 Report Share Posted June 29, 2006 Nice work! It'll be some time before I have the motiviation to etch my own boards again, but building one of these sounds fun :) Have you considered the options with triggering? If all it needs is a 5v pulse the seq I'm using on my 808 will work nicely ;D Quote Link to comment Share on other sites More sharing options...
illogik Posted June 29, 2006 Report Share Posted June 29, 2006 ;Dnice work people, i won't have any spare time till 2056 with all these projects... Quote Link to comment Share on other sites More sharing options...
Jaicen Posted June 29, 2006 Author Report Share Posted June 29, 2006 As far as I know, the circuits for both the DR boxes can be triggered with +5v 10ms pulses so yeah they should work nicely with your design. At the minute, none of my voices include accent, as the way that the DR's work it is to have an output amplifier with variable gain, depending on the accent setting. It would be possible to duplicate this 8 times for each voice, but i'm not sure how useful that would be. If it was being live, I guess it would be ok to have accent for the drums and one for the hats/cymbal. I'm not sure about any of this really, just thinking out loud.

DrBunsen Posted July 8, 2006 Report Share Posted July 8, 2006 $1.95 ... serial in ... up to 50 volts out on 8 pins at 150mA continuous/500mA peak ...Sparkfun strikes again Quote Link to comment Share on other sites More sharing options...
seppoman Posted July 8, 2006 Report Share Posted July 8, 2006 BTW, there´s also a TPIC6A595 version that can sink up to 350 mA/Pin continuous.Seppoman Quote Link to comment Share on other sites More sharing options...
