MonoMiK

Okay, my holidays started and i found the time again to continue working on this synth. So i completed the VCO mixer module, which has TWI-controlled analog switches (okay, standard 4053 analog switches with PCF8574 TWI/I2C I/O ports :) to provide the waveform switching. Two sub oscillators, one per VCO, are also on this module, finalized by 4 VCAs, which are controlled by the front panel knobs but are also able to get modulation signals. The 4 VCOs output the main and sub signals of the 2 VCOs.



To test everything, i needed to create a more sophisticated setup with a microcontroller switching the waveforms, while the selection vomes in via MIDI control changes. I also needed the wiring between the dual VCO module and the VCO miver module, so i decided to just add a bit more and include the VCF and the ADSR modules and peek into the current state of the development by listening to it. I think, the result is quite fine:



(The left one is part 1, the right one part 2)

Another new piece of electronics has been added. Those funny things are the small LED modules which go to the front panel. They are connected to modules and the backplane via adapter boards. Details will be seen in the allover construction photos which will follow in the future.



Schematics and my veroboard layout can be found in the Wiki article about the MonoMiK

All this was done in 2008, but since 01-Jan-2009, i have a new hosting plan again, which enables me to re-activate the website. This is one of the first posts on the new server with lots of more space :)
