DIY hardware programmer for Kawai K3m Synthesizer and CR-78-clone
YouTube via stereoping | September 26, 2010
"This video features my 2 last diy-projects: a hardwareprogrammer for the Kawai K3m and an analogue drumsynthesizer. Sorry for the shaking, had to hold the cam the whole songrecording.
1. I made a hardware programmer for my beloved kawai k3m which is normally painful to edit. It's made out of an old keyfax phatboy which is quite useless normally because it only sends mostly useless fixed controllerdata. I spent it a new brain of an atmega8 and connected it to the multiplexers and switches. After some programming it now sends sysexdata suitable for the K3. Of course any incoming mididata is merged through. Notes have priority before sysex to prevent notelags. There are 3 color-modes which can be switched by a 3-way-switch in the upper right corner of the controller.
2. Second featured DIY-project in this video is my "Viscand 16" - a frankensteinproduct of a VISCount 160 and the rolAND cr78. It eats mididata and listenes on 16 notes to trigger the voices. Its hard to find coils today, the CR78 needs some for filtering (tambourine, metalbeat aso.) . I tried to overcome that by filtering the noise with a simple opamp-bandpass before it gets into the circuit. Another try was to use old relais-coils together with some capacitors, well it worked somehow. The sound is quite near by the cr78. Although i still got some problems with a clean accent-amp the video shows how it sounds.
Other synths used: v-synth (suqareblip), polysix-plugin, albino-plugin (Bass) and dynacord studioquad for reverbs."
