DIY analog synth project (Steiner Parker Type VCF Version 2 Demo 1 7mins Acid Test)

Published on Mar 26, 2018 Adamski A.

"Here is the first in my short sound test demos, showcasing my Steiner Parker "type" voltage controlled filter which is a combination of ken stone and yves usson's designs. I replaced the diode string with npn transistors to see if I could put a nice twist on this very well known circuit, also the capacitors have under gone some experimentation.
Please leave your thoughts and comments ,either positive or negative on the sound I hope you guys can chip in and give this circuit a go.
I definitely see some potential for a eurorack module on this , so if anyone is intrested in helping develop this circuit further feel free to message me."

"This is a 4-voice analog synthesizer with 24 built-in programs. It has a powerful sound and has many knobs and levers that allow you to change the quality of the voices as you are playing it.

I had a lot of fun using it in the 1990s, when I played it in an indie rock band for a couple of years. It worked great for reproducing some of the sounds heard in songs by The Who and other 1980s bands. When the sound of the band changed, I put the keyboard in storage, and it has been there ever since. I just took it out this year (2018), and found that all the presets and filters are in good working order, and it still makes that delicious analog sound.

It has not been serviced since I have owned it.

It is in good working condition except for one thing: when the pitch bender is bent up, it lands on a note that is higher than the original note played. However, when the pitch bender is bent back down, it lands on the correct note."

TR-9090 driven by Midibox drum sequncer

Published on Mar 27, 2018 wotatwaat

"TR-9090 driven by a Midibox drum Sequencer that Thorsten from Midibox kindly modified so the firmware supports individual accent for the voices. It is a fantastic sequencer. The Tr-9090 has a few mods, CV control for various parameters. Here the Beatstep is controlling the pitch of the bass drum and occasionally the hi hats. The hi hat eprom has been expanded so you can switch between standard 909, 808, or flanged hats. Noise frequency, Clap reverb amount, tune, filter. Rimshot tune and a few more."
