DS 7 clone

Hi,

I thought that information was on the site, but it seems it isn't, so I'll have to search Smile

I tried to trigger my drum synths with the CV outputs of my 80's Vermona DRM Drum Machine (not the DRM-1 Drum Synthesizer they make now). It has a 30-pin cable for separate audio outs for almost every sound and triggers for all sounds plus some extra triggers (16th notes and some triggers you can program on the Vermona). I can trigger all drum synths with the audio outputs, but only the Amdeks (and the Coron/Boss/Washburn Handclap modules) can be triggered with the triggers.

I will compare my trigger inputs with those of Marc Bareille. I discovered years ago that I could add such an input by connecting a jack on the wire between the Piezo cell and the Sens pot, but I see more components on the clones, so if you have no problems I should try to do something like that.

I have no drawing of it by Marc Bareille (I suppose I made one myself, but I can't find it), but this is how he explained the CV mod to me:

Oh and for the Amdek PCK-100 (quite similar but with both sweep "up" AND "down" and multiple wave types for VCO and LFO) there's a lot of info (schematics, pcb, mods,...) on my site:

It's the same as the Boss PC-2, this was a DIY kit version of it.

I see a lot of people complaining about the ca3080.
I have a local shop here who has lots of these chips still. If its relly that important i can buy and send some.

Thanks for the tip, dnny. I had my suspicions as to the workability of log vs. lin. Now i will order lin pots and be done with it.

I am so confused. Hey guyz I am newb DIYer.

I just dont understand what exactly the DS7 does, I have been looking on google and no info.

I know DS7 is a drum Synth, now it can be triggered to be connected to a Pezzio, do you have to sample a sound? How would you end up making one, for a complete drumset. With toms and everything.

Making multiple Dual DS7s and then having them connect through one output?

Any help is quite appreciated.

It doesn't use samples, it's an analogue drum synth. That means it generates a tone and mixes that with noise and then it decays away like a drum would. It's a very electronic kind of drum sound.
Each DS7 is 1 drum, so for a full kit you would need multiple DS7s and a method to mix them together into 1 or 2 outputs.

I would build DS7.I love how it sounds!But I have some question before building it

-capacitors are all electrolitics?
-Can you tell me the exact value of each capacitor?I don't find an exact correspondence between part list & schematic.For example:In the part list C1 is 10 uF and in the schematic C1 is 3u3?which is correct?
-I have CA324 & a HA17324 instead of LM324.Can I use them together?Or can I have problems with HA17324?

Oh dear- because of the alphabetical ordering, the DS7 has taken the place of King Klee. We cannot allow this!!! Exclamation
