Brilliant Companion for Any Semi-Modular Synth!

For QUADTEC-101 - A DIY Open Source Digital Oscillator

Very easy build, helpful seller, and a great module for those who may already have a semi-modular monosynth. Nice, rich yet charmingly digital timbres with CV control perfect for mixing into any patch, and the internal "VCA" makes it a very capable voice on its own. The fact that you can run this off a 9V battery without Eurorack power or case? Perfect for beginners! And all that is not even getting to its quadraphonic applications... let the outputs phase around, process each out through other modules and mix them back into a T H I C C stereo image!

The only things to look out for are that the 1V/Oct CV only starts tracking from about C3 and that there are (developer recommended) upgrades worth looking into (the possibility of a drop-in DAC upgrade and different resistor values for louder output). Also, if there's ever a Mk2, I would appreciate greater CV control over individual parameters, though that might just be wishful thinking :)

All in all, a perfect module for those just starting down the rabbit hole with a monosynth or two, or for those looking to sacrifice more of their wallets to the patch cable and LED gods!

Thank you so much for the wonderful review! I am working on a successor which will drop the quadraphonic capabilities, and trade them for CV control over all the parameters. It will also be smaller :)

Thanks Aditya!
