Vintage Synths

Introduction

Most of our synth stock is no longer for sale (we are using them to design the MIDI programmers), but we still have a wide assortment of vintage synth memory cards, along with parts and keys in stock. Contact us to purchase or use the Paypal buttons below.

Yamaha GS1 and GS2 Memory Mod

The memory strip readers on the GS1 and GS2 are notorious for leaky caps, which destroy the traces on the board and several NLA (No Longer Available) ICs. So, unless the cap leakage is caught soon enough, most reader repairs are not trivial. Our memory mod replaces the volatile memory with a larger EEPROM, containing all 3 preset library volumes and most of the diagnostic presets.

 
GS2 ModGS1/GS2 memory mod (with GS2 preset library): $256

Note: Installing the memory mod requires opening the GS and swapping the RAM IC, along with drilling a hole in the faceplate (or replacing the card reader with an insert) to accommodate the bank selection knob, which should performed by a qualified technician.

Note: The GS-1 requires two memory mod daughter boards, while the GS-2 only requires a one. The GS-1 will not be able to mix presets, since the card reader does not function with the memory mod. However, we can preload preset mixes upon request (additional fee will apply).

We also offer GS2 memory strips ($8/ea) and samples of each preset (download demo).  Samples are in WAV format with presets for most common sample players (Logic EXS24, Kontakt, Reason NN-XT, MachFive, SFZ).   The full sample library can be purchased from our sample store.
