Roboto - Synthrotek

Some pics of a recent DIY build - the Roboto eurorack module by Synthrotek.
Its pretty cool .. reverb, vocoder, pitch shaper, vibrato , etc ... very flexible.

I bought a barebones kit which included the PCBs, faceplate, a vactrol & one microcontroller ic....labeled R1



The heart of the module is the HT8950. It is a CMOS LSI voice modulator IC which provides seven steps to shift the frequency of an input voice, producing a dramatic change in the output. The HT8950 provides two special effects: vibrato and robot. The vibrato effect is generated by alternating the frequency of an input signal up and down at a rate of 8Hz. The robot function, on the other hand, converts an input voice into a robot voice

R1 is a PIC16F1823 microcontroller. It's already programmed.
