Eurorack Module around a S2 Waveblaster and an EWave waveblaster
People whom have visited my YouTube Channel before, know I'm fond of the Yamaha YMF chips (like the YMF262 and YMF704) but the prices are soaring.
Did I bought an YMF704 @AliExpress for 16 euro prior to the Covid pandemie, now I can't get the same chip from the same supplier for no less than 80 euro!
So, no YMF chips for me...
But: There is SerdaShop.com where they sell Waveblaster cards which are very easy to adapt to EuroRack standards.
I got two of them, the Dreamblaster Synth S2 General Midi Daughterboard, which resides in the 4HP (=2 cm wide) module. This is the most simple of the two modules, it has a optocoupler midi in, a 12 volt to 5 volt linear voltage converter (7805) and that's it.
You can add a simple amplifier to crank up the output to euro standard.
The 6HP (3cm) wide module also houses a STM32 processor to read the incoming midi for display properties and with the rotary encoder you can set the instrument to 1 out of 16 channels (like an internal patch-bay).
It also shows a splash screen, which can be chosen for the S2 or the Ewave waveblaster by setting/removing a jumper.
