laser cutted case
Yeah!
assembled case
All parts fits fine
top panel engraving
Single line engraving a little bit dirty but much accurate than double line.
assembled case
mbseq case test assembly
Found cutting error - no hole for 4-th encoder =)
LCD windows
here fits fine too
standoff with plasticine mold
standoff is glued with cyanoacrylate
plasticine mold filled with epoxy
fastened stand-offs

mbseq guts
mbseq assembled
The final step is to make matrix wiring like in Wilba`s MBSEQ for control surface and leds. Now the bottom line of buttons not used.<br />Vacant DOUT and DIN modules will be used in MBFM, which is next.

Tired of drilling =)

MBSEQ MIDIOUT Fix
like at 3.3 v midi devices.

SD slot desoldered from broken camera, piece of protoboard and aluminum profile.

CS back
SwinSID test stand
Made quick minimal surface, sammich-style: 13 buttons + encoder with button and 4 leds for L/R, PLAY and LFO. There’s 4 free leds, has no idea what i need more.
MBSID slave core
Nothing superfluous. 4pin Power+midi I/O from Core J11. One pin for CAN and 2x4 pin to Stereo SID module (J14 combined with unused pin)<br />Did i missed something? :whistle:

Stereo CEM3379 VCF/VCA for MBSID
It’s actually 2xCEM3379 Shruthi filterboards without power regulators.
MB Stereo SID
Finally it works!
2xMOS6581 → 2xCEM3379 VCF/VCA (CV range 0-5V for Cutoff/Resonance/Gain)
modified AOUT_NG to output 0-5V from 12V bipolar supply.
perfoboarded CS and modulation matrix with cheap 8x8 led matrix from ebay.
MBSeq TPD module
MB Stereo SID
Project begins to take shape.
2 x 6581 SID, AOUT_NG, CEM 3379 Stereo VCF/VCA, Bipolar 12/5v power supply from DVD player, enclosure of the soviet calculator Elektronika MK44.
Stereo SID
Still not shure about this CS.
Looks nice!
