Price: 25€ Net (plus shipping costs)
VCO Board for Welson Syntex
In stock
Features: Reproduction of the VCO board for the Welson Syntex. Strictly identical to the original in design and size, it allows for the replacement of the latter, which is notoriously fragile and ages poorly. The board is supplied bare with the layout diagram and component list.
Price: 25€ Net (plus shipping costs)
KAS (Keyboard Assigner) Board for YAMAHA CS-80/CS-60/CS-50
In stock
Features: Reproduction of the KAS board for Yamaha CS series synthesizers. Identical to the original in design and size, it allows for direct replacement without modification. The package of some hard-to-find components has been replaced by more modern references, such as the CA3140N in a DIP8 package (for purists, the CAN model can still be mounted). The board is supplied bare, along with the component placement diagram and bill of materials.
Price: €50 Net (plus shipping costs)
SH (Sample & Hold) Board for YAMAHA CS-80/CS-60/CS-50
In stock
Features: Reproduction of the SH board for Yamaha CS series synthesizers. Identical to the original in design and size, it allows for direct replacement without modification. The package of some hard-to-find components has been replaced by more modern references, such as the CA3140N in a DIP8 package (for purists, the CAN model can still be mounted).

Price: €30 Net (plus shipping costs)
UNI-DET (Unison & Detune) Board for YAMAHA CS-80/CS-60/CS-50
⬤ Coming Soon
Features: New design for the SH board for Yamaha CS-50/CS-60/CS-80 synthesizers. It replaces the original SH board and adds two new functions to the synthesizer:
– A Dynamic Unison mode. Pressing 1 key triggers all 8 voices, 2 keys trigger 2 x 4 voices, etc. Beyond 4 voices, note assignment reverts to “normal”.
– A Detune mode that allows for a slight detuning of the 8 voices (between 1 and 5%) which produces a rich and full sound.
The UNI-DET board mounts in place of the original SH board. It is compatible with the MIDI interface for CS-60 V1.3 and future interfaces for CS-50 and CS-80. Due to its design (16-bit 8-output DAC), it will eventually allow for the addition of an Autotune function to the CS series, as well as programmable microtonal scales.
Price: TBD for now.
PRG (Programmer) Board for YAMAHA CS-60/CS-50
⬤ Coming Soon
Features: Original board for Yamaha CS-60 / CS-50. It adds the ability to edit the parameters of each synthesizer preset on the fly and save the result in one of 28 memory slots (2 banks of 14 patch memories). The front panel's Preset button block is retained to preserve the synthesizer's original appearance, but all mechanical parts (switches) are replaced by a new electromechanical block, combining LEDs and tactile switches, manufactured using 3D printing.
The PRG board, with dimensions identical to other CS boards, mounts into the CS-60 / CS-50 rack, similar to MIDI interface boards, with which it is compatible.
The board then recognizes MIDI Program Changes as well as synthesizer parameter control via System Exclusive messages, and in a second development phase, patch memory saving, also via Sysex.
Price: TBD for now.
