MONOLITH

Bluetooth Receiver with Envelope Follower

Easy to use and quiet solution to streaming found sound from phones etc. via Bluetooth into your Eurorack rig with a simple bipolar envelope follower with attack and release controls tied to the audio output.

Output is mono (the stereo channels are mixed within the module)

Output from the incoming Bluetooth audio is boosted to euro levels while a simple attack/release circuit with a good decay length attempts to follow the envelope of the output. This is best used for gated signals and drum beats. But anything with a significant degree of amplitude dynamic will allow the follower to modulate in accordance with the signal. At zero attack and release it'll output what is more or less a copy of the audio signal as a unhinged CV source.

Ideal for running found sound, YouTube videos, phone conversations etc. into the rack.

A quick demo video to give an idea of what it does.

running a drum track from Sunvox on the phone into it and using the envelope follower to modulate a filter and VCA.
