Only thing you have to take care or better i would say make choices,is the D-shaft potmeter position VS the knob style/brand you gonna use and final user alternatives.
The nice thing is that it's a 9mm potmeter. It can be replaced by a round shaft Alpha potmeter.
So one is free to put what one wants.
For the prototype, I have not decided yet which way it will eventually be,
but I don't have to change the PCB if I want to try other potmeters.

Both have their advantages and draw backs, one has a better feeling but costs about the double of the other.
But knobs, for now I was thinking on using black aluminium knobs, but other proposals are welcome.
We only have to keep in mind that some knobs are very expensive, as well as using 'cheap looking' knobs are not preferred on this system either.
My renders are with the black aluminium knobs.
All feedback welcome.

I'm a big fan of the Sequential Circuits style black aluminum knurled knobs... those would look awesome. I know it is premature, but were you planning to offer any parts along with panel/case/pbc? If not, group buys should help with the costs.

It's still premature, and honestly, I don't know yet if I should provide components or not. But thanks for bringing it to my attention in this phase of the project.

Yeah, after I completed the DDRM, I swore off any more sdiy projects. That lasted about a whole month. I can't wait for this to arrive, but my wallet hopes it waits a few months.

This is trivial and effectively totally irrelevant, but I've got a question about the interface buttons.

Wouldn't it be lovely, and much cheaper to use opaque plastic caps which reflect the rainbow of the JP-8's middle line rather than illuminated buttons?

I've been messing around with the MSQ-100 lately, and I must admit these little low profile squares in off white, grey, pale orange, and sky blue are really attractive and touchable buttons. Somehow a lot more friendly and inviting than led illuminated buttons.

Might be cool to do a true to the inspiration color scheme with button caps?

What about those little soft touch opaque ones w LEDs behind them? A modern touch for sure, but nice buttons!

Hello all,

thanks for the reactions.

The switches I'm using here are from the B3W 9000 and 9010 series.
Image
The special functions have a colored transparent cap, all the others (light yellow in the render) have a milky white cap with yellow led.

I do like these rubber (silicon) dome switches as well, but I'm afraid it's going to get pretty expensive if I have to reflect all fixed costs to the number of units this synth may sell. In case one may have some good references of where to buy, It's not too late to change them if mechanical constraints allow.

Updated the preference list.

I must admit to being confused as to what people are signing up for. Does the front post need updating? It says voice cards are SMD only, premounted and a mostly through hole control PCB. Now there's alist for SMD or through hole voice pcb's as well? Can someone please clarify?

Edit: Sussed it out. Put me down for the SMD prepopulated option.

Would be great to DIY a fatar keybed onto this.

Indeed.

The sourcing for avatar OEM boards is very problematic, and affects my pro one project as well. But, stay tuned as I am insterested in trying to get something going with regard to this.

Edit: Audio track replaced. End Edit
This audio track is a multitrack recording of the JPTR's 8 single voice board.
Chorus and reverb are added by FV1 home written algorhythm.
Apart from volume balancing, in which I'm not a specialist, no further post processing.

Dunno what you mean by avatar boards. Doepfer appear to have 49, 61, and 88 key fatar's in stock atm.
