Lovely! Might have to pick up one to accompany my Boardweevil2012 in the future

Yeah, I felt I was missing a 'board' design. Should have got it out before Christmas really - the first batch was built but took me another month to clear other things and do some (very damn basic) documentation.

Outstanding! That plus headphones, tucked in a backpack, for walks in the woods. :tu:

Edit:
Okay, instead of headphones...

Though you might get some pushback!

- minus headphones
- plus power amp to show all these other littler chirpers what is a real chirp!

Such a cool little guy. I was tempted, but figured I'd wait for now... Had to pick up a DRM2 today, instead. :) I can see picking up one of these in the future, though.

Beautiful little Chirper, no doubt even more fun with the touch points (really intrigued by their control - lovely graphics!). Sounds just as good as the original.

Is it exactly the same synth minus the banana jacks?

It is very similar but I had to do some distinct tweaks to get it running off a single battery. + doesn't have things like sync.

I did a pair of proto full-size chirpers with touch expanders (some might have seen pics on Instagram via Palle and MengQi) but there were design niggles I didn't like, especially on something large/expensive like that - so the small board standalone approach seemed a much more suitable place to install the touchy stuff.

Glad you solved the conundrum Tom, the Board looks rad!

Are similar plucky pining sounds still possible from the filter? Would anything be able to be soldered to banana jacks to modulate?

Absolutely!

I knew this would be asked! I don't really recommend connecting external machines (go for the proper Chirper!) and said that on the instruction sheet. Sure there'd be ways, but... as always I design for the specific purpose and this one was for portable exploritations.

Some minimal descriptive ideas on touchplates & combinations (not that I know them all by any stretch!) - there are some small labels on the back:::

Each OSC has four plates:
- on the outside the one above the other are square-wave (SQR) output on top and triangle (TRI) wave below
- the next block in is the CV input - try touching an osc output (either osc) back into this.
- the most central block for each connects to the comparator input (COMP)of each oscillator. Really it just seemed like an interesting node to allow access to!

The Filter has 8 plates:
- the lowest two are Filter CV (similar to Osc CV) on the right side and Filter Input on the left side. The good thing with the input is that you can turn down the Drive control (yellow knob) to mute input to the filter and then touch a signal across to the input.
- the other plates are inputs and outputs for each filter stage - Lo/Band/Hi outs and points to their input summers (labeled eg BPND = bandpass NODE)

The two triangular plates connect to V+ and V- (via current limit resistors) - the theory was that touching these along with one of the CV inputs would raise or low the section but I don't think it quite works like that in practice.
- the centre square connects to 0V and might be useful for muting certain parts or otherwise mutating behaviours.

The bit at 03:21 is pure sci fi coded message in space. Nice recording! :party:
