BENJOLIN 4U

Post by anto32 »

Hi,
This is the Benjolin, Buchla compatible.
Thanks to Rob Hordijk, the help of the brilliant Mr Dave Brown and the perfect panel work of Julian (Thebeast)

Early proto

Description :

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 : 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. When pushed, it changes the pattern of the Rungler.

- 2-pole VCF with Rungler CV control and attenuverter.

I'd be interested in a LW Serge version of this.
If at first you don't succeed read the instruction manual.

I actually worked on a layout, but I got no time to do it.
It might need some more labeling, but the main idea is here.

My 4U Benjolin. IIRC it was a FPE panel with Lazertran art. I'd be happy to share the layout and art if anyone wants it

It is Anthony's design, but, from conversation, i think that his plan is to do an initial run, and then, at some point, release the fpd.

The panel photo in the first post was engraved. When its finalised, it will be silk screen printed.

I will certainly be printing the primary run in the usual materials / inks but its very much Anthony's project, so his call on how the parts are released.

(i just chop metal!)
