hi!

I am working on a synth diy project whose aim is to create an analog drum synthesizer with digital step sequencer control. The design and building of the project was documented in a blog (someone else on that forum already found it, see here
) now i'm just wondering what you think about and if someone is interested in re-building it

I can't see any schematics on his blog. Without those it's pretty hard to recreate.

StoneRose,

the blog link you posted gave me a "page not found" as you typed it as a relative URL. I changed it by prefixing with http:// to make it absolute, guessing that's what you meant to do Wink

I'm interested in building a drum synth and haven't found the right circuits yet-- so I'd be interested in more infio also.

Hi:
I´m a little bit obsessed with synthetic drums, I builded a TR-9090, I´m
building a TR-808 clone, and I have plans for build a lot of modules, and
at some point a drum sequencer.
I followed the development of your drumsynth with a lot of interest, and
at some point, when I finish something of what I´m already building,
I will love to build some (may be all) of your modules, or the sequencer.
The drumsynth sounds really nice by the way, congratulations.
Thank you.

thank a lot for your interest and replies.. i'm currently transferring some content of the blog onto a 'real' website, the schematics will certainly be downloadable from my new site at the latest in two days
Other question: is the some info available on the net on building a tr-808 or 909 clone? after extensive searching i found some schematics of the tr-808 (which served as an inspirational source for my project)
what do you think about doing the drum synth in a modular way, this means building/soldering the individual modules separately and connecting them to the sequencer in a later stage? this would allow to exchange and vary some sound modules? For the prototype i hard-wired the sound modules to the sequencer part but it's definitely possible to connect them in a modular kind of way

the schematics are online and accessible here
@sebo: thanks for the links posted!

Thanks stonerose, looks like you have done a lot of work on this.

I'll definitely build some of your drum designs. I've built bits the 808 kick and snare circuits and some twin-t toms so I need some cymbals. You hi-hat sounds great a looks interesting.
