For the second run I am leaning towards these panels so far: 291, 180ish dual Music Easel EG (lanterman PCBs) and the 123ish dual flop sequencer (J3RK pcbs).

Someone mentioned that they would prefer the lines were a little thicker on the panels. I could do this but it would mean the subsequent panels would obviously have slightly bolder lines than the 258... feedback?

I'd love to have a buchla panel for a dual toppobrillo quantimator.

I understand that this may not be popular as it doesn't really fit with the 100/200 series style of all the panels so far, but I think that it would interface well with all the 'quad' panels that will feature in these systems - it'd be pretty easy to sequence chords for example.

I thought i'd mention it now as it looks like there will be a run of pcbs soon.

I guess it also depends on if people are building their oscillators for 1v/oct or 1.2v/oct. I'm building mine for 1v/oct so this would be perfect for me but maybe not for others.

Agree with Valis on the lines. They look fine to me

(Shit, I wrote a big reply and then my laptop crashed!)

Sounds good on the next batch! I will definitely want the 291 and 180 panels, probably 2 of each for good measure. Will the 266 panels be part of this batch, or are you waiting for Roman's panels to start shipping? (No problem here either way, just curious!)

For the 291, I'm not sure how things are at the manufacturer's end... but would it be possible to use the same layout, but have two drilling templates? One with 2 output holes, and one with 3 output holes? I am very much in the 2 holes/bp-only camp.

The 123/FlopSeq is a cool idea! I have 2 FlopSeq PCBs (one here, one in the mail), but have them slated for other purposes at the moment... I'd also prefer a more "authentic" Buchla sequencer; a replacement for the original 123 would be easy to perfboard, for instance. (A pulser/clock would also be helpful.) Are you planning other sequencer panels? If not, I may grab one of these panels...

I know before it was mentioned that a 111 Ring Modulator PCB might appear. If that is the case(?), it might to best with a Lanterman Timbre/Crossfade PCB - both being audio modulators. (And considering that the 111 panel was a waste of space + the Timbre had no original panel).

If that is the case, then perhaps 2-3 Lanterman Preamp/EF panels could be combined behind a 130/230 style panel?

If my only option were a Lanterman Easel Timbre/Crossfade/Preamp/EF, I would pick up a panel, but I would much prefer two if one was a multiple Preamp/EF, and the other was a more complex Timbre/Crossfade/RM unit.

Also looking forward to a 106 mixer panel. While not the original circuit, it can be achieved with 3 CGS DC Mixer PCBs. I may try to breadboard the original, to test it, or even just make a simple version with some LM741s.

All the designs so far look awesome, BTW!! (Not to mention the completed 258s!) Looking forward to my panels + synth!
One quick question: on the CVP, are the additional ins/outs per channel just intended to be multiples? (Or did I ask this before? If so, sorry...)

(Oh, and if those Zthee Klee things ever happen, I am grabbing one! Granted, it is not authentic Buchla, but it is an effing Klee!)

I just wrote a novel. Enjoy:

I am going to get a quote on the 266 panels soon. They will probably follow the current batch by a week or two.

@dio - 291 hole drilling – I’ll be honest, I don’t want to get into variations in panel designs. It will get expensive, and dealing with who ordered what type of 292 panel is just one more PITA task on top of changing order numbers, changing addresses, etc. The 2 or 3 hole thing isn’t set in stone. I need to play with the design on paper with physical jacks and such. I’ve done that with the 2 hole but not the 3…
I will only do 3 holes if it doesn’t change the surrounding design and if the jacks look ok and are usable in that proximity to each other (still need to check). As a compromise I wouldn’t mark them. You would simple gain an extra BP out.

@everyone - As it is, I already have people wanting variations of the designs to work with proposed roman designs or just personal preference stuff. As much as I want to help people out there has to be a compromise somewhere. Paying for new art/layouts and the increased cost of doing separate small batches of individualized panels is expensive and inefficient. It may sound selfish but I’m also not crazy about spending my time working on panels I won’t be using (i.e. 2 variations of the same panel 292 and 292c, etc.). I appreciate feedback and suggestions but I would also appreciate some flexibility. Everyone has an opinion and there are quite a few issues with the panels where the opinions are polarized.

As far as the next batch goes and which panels I choose, nothing is set until I announce ordering. Panels are subject to change. Keep in mind that there will be multiple batches, be patient. I will try to get around to everything. If it doesn’t happen this batch then maybe next. With that, there are a few things in flux which may alter current plans. Such as:
- Sequencer: J3RK mentioned additions to the flopseq. I might want to wait until he announces his next run before finalizing the panels. I could work on the 245/6 panel instead. However, I have not built a pulser PCB yet and seemingly few have. The one instance of a documented build omitted a lot of features. I have a good idea on what features to include and not include but it would be nice if someone on this board built one and could verify exactly how some of the features work and if they are useful. I’d like to know, for instance if enable and NOT work basically the same as the start and stop functions indicated on the 145. I’d like to know if the extra switches would be useful as gates if brought to the front panel. Since PWM isn’t on the PCB it would likely not be a feature on the 245/6. However, it could be replaced by the extras that the pulser board has such as the inverter, CV enabled switches, addition outputs A (constant) B (enabled)…
- Fluxmonkey was working on the 111 PCB. You would have to ask him about a status.
- I agree that the timbre may be better paired with something like the 111 or the lanterman blanaced modulator. Someone mentioned that Aaron might sell his current boards but they need to be modified. Either way it would be nice to know we can get PCBs before pushing ahead.
- I could do a dual preamp/envelop follower easily enough. I’d need a second PCB myself as would others I would guess. Does anyone know if Aaron still has boards?
- Someone else on this forum has been working on easel boards and might offer them. I don’t want to speak for them but if there are runs of good, readily available boards it would be nice to design the panels around them. This person did mention that they were starting with the boards that lanterman hadn’t gotten to yet, including the complete complex oscillator section. Exciting news if it happens.
- The 106 mixer panel might be a smart move for this since we could just use CGS PCBs and we are waiting to find anything out.

I don’t know anything about Zthee’s plans for the Klee panel. I’d be happy to get one myself.

RSFC - sounds fine!! And, once again, thanks for all your work on this!

Yes, I agree that it makes sense to wait until PCBs are available before designing panels.

Regarding the pulser, I have a PCB and could try to order the parts needed to build it up. I have an idea for getting the pulse width too.

That Klee panel was desgined by Muff member jooks.
