Buchla Benjolin Test 1
Published on Jun 7, 2019 Todd Barton
"A new, very limited edition of Rob Hordijk's Benjolin project in Buchla format by Anto."
Update: second video added to the playlist above.
"Audio outputs normaled :
- Square 5 pk-pk
- Triangle 4 pk-pk
- XOR 5 pk-pk
- PWM 5 pk-pk
- VCF Out is approx. line level
I've added a jumper to disconnect the PWM that is internally wired to the filter.
- 1.2V Inputs _ these vcos are not super stable but 3 octaves tuned decently_ there's trimmers on the back to adjust each vcos
- CV Attenuverters
- Clock In & Serial In : Feed with external signal (at least 2V) Trig, gate, or CV. External is activated when switch is down.
Pulser from 208 is a bit to short to fire it. Works with 281, 245, TSNM, 259 square and saw waves, uStep, Klee sequencer, LFO, 266 outputs, 208 envelope...
- Bit 1/2/3 : Gate Out 15v - when led light on : Gate=0
- Stepped : It's the Rungler CV output, 8 stepped voltage (S&H sort of). Maximum range from 0.5 to 12v. It can be trimmed.
One "scale" I find useful to shift the stages of the 245. 1,2v/2.6v/4v/5,4v/6,8v/8v/9.5v/10.8v
- Switch mode : 8 steps / Random / 16 steps
- PushButton : Manual Trigger Serial In = change the pattern of the Rungler when pressed.
- 2-pole VCF with Rungler CV control and attenuverter."
Original prototype.
