Obsoletetechnology Low Cost CV-Gate to Midi Converter

"The circuit is mainly based on an analog to digital converter with a midi output. It is intended to be used with analog sequencers, modular systems or signal generators, wherever a conversion of analog signals into Midi messages is required.

The module provides 3 CV-Gate input channels and can be configured to handle these 3 CV-Gate input channels as monophonic or as polyphonic input sources, either generating 3 independent midi Note On/Off messages with different midi channels, or in poly mode, generating note messages on one common midi channel.

Additional to the CV-Gate inputs, the module provides 2 more input channels for CV signals, which are converted into Midi CC messages."

Midi to Trigger Interface From Obsoletetechnology

"Low cost, low part count Midi to Trigger interface with 10 Outputs.

This Midi to Trigger interface generates a TTL (5V) trigger signal per note over a range of ten notes. It can be used for example as a midi interface for vintage drum-expanders or as a multiple-trigger generator for a modular synthesizer. I developed this module in order to modify my Tama TS305."
