Thanks for the kind words !

Here's an 'old school house music' video from CarbonTony testing out
the previous proto [ different layout ]

https://www.youtube.com/watch?v=iIqzDajF6rA

RHS plays some PLAITS chords, [stage 4 & 5 ] using random gate mode on stage 4
LHS plays bassline, using different per stage clock div on the gates.

Looks great.

Will it be possible to buy just the PCBs or maybe the Roland format kit but without the panel? I'm planning a 5U version.

Hello

I am hoping to offer a 5U version in the near future, once
the Euro and Roland are sorted.

As you guessed, the 5U panel is quite similar dimension to the Roland
100m. But obviously will need bigger jacks !

Hi, I also expressed an interest several pages ago.
So, just to make sure - I am intested in a 100m format unit, maybe two depending on price.

Hi

Quick update.

Panels are ready !!

But due to the Coronavirus in China, some parts are not yet ready.
Hopefully it clears up quickly and people are not too affected by it.


Keep healthy !

Rick. Looks fabulous man!

I have an old PCB and pic from years ago could I get extra panels and switches? Will it work with the old versio ? I'm not 100% sure but I'd probably like 2 eventually. Still up for a full new kit in 5u motm regardless.

The thought of wiring up the rotaries has put me off. Maybe a basic one just using pots for the older version.

Anyway thanks again for doing this.

Regards

This is a new version, which uses different switches, so not compatible with the old one, sorry.
Also as the new kit uses pin conectors between PCBs, it is a lot less pain to wire up.

Many thanks

Hi

Sorry for the long delay, still waiting for the Chinese factory who
supply the switches to get back into full production.

Hopefully a couple of weeks, fingers crossed.

Here is a picture of the finished module with anodised aluminum
panel, and RAL 9002 screen print.

New software additions now included scale quantisation of notes,
firwmare upgradeable with MIDI sysex, and forthcoming will be
clock multiplication for those dumb Korg boxes with only 2ppq !

Panel PCB now has micro switches to select TRS MIDI spec [ type1 Korg, or type 2 ALM]
Kit will be supplied with 2 x TRS MIDI cables, and 1 x Special stereo to mono TRS cable for CH2 CV & Gate socket.

Thanks.

Knobs = Taiwan’s finest !
But quite a bit of effort to push them on,
after which they don’t appear to want tome come off.

Strangely they are also available in transparent finish .
