A couple of projects I have been working on in the past. Unfortunately I have almost no photos of my modifications, so this will have to do..
This Crumar has been heavily modified. In order to reduce weight large parts of the original circuit have been replaced and built into a new case. Both the polyphonic and monophonic section were midified and the original heavy keyboard replaced with a much lighter midi keyboard.
In addition various features not existing in the original Crumar were added such as:
- Midi input
- Midi learn
- Two different keyboard split modes (with arbitrary split point)
- two selectable monophonic priority modes
- gate retrigger (retriggers the mono synth on keypress)
- pedal input for filter
Roland TR-606 extension box
This is a box which attaches to the side of a 606 and adds a lot of features.
Cymbal and open hihat got an attack/decay envelope which is fully sensitive to velocity. This gives you independent control over the attack and decay times and the volume of the instrument.
Also I added a ring mod variant to the existing six hihat/cymbal oscillators using XORs. Gives you a great range of metallic sounds.
-Open Hihat attack, decay [velocity sensitive!!]
-Cymbal attack, decay [velocity sensitive!!]
-Control pitch of two oscillators for the cymbal and hihat metal sound
-Chose hihat sound to be, oscillators, two oscillators with ringmod, four oscillators with ringmod, mix
-Adjust hihat highpass
-Adjust cymbal highpass
-Adjust hihat+cymbal bandpass
-Adjust cymbal bandpass
-Low tom pitch
-Switch tom noise
-Snare noise amount
-Snare highpass filter
