Thread: Flame C-3 Knob Recorder
The 1010 Music Toolbox is also capable of recording CV (even audio). It has two audio/CV inputs that can be used in mono or dual mono. It can play back up to eight channels of CV or audio. You can also SAVE and LOAD your CV from microSD cards saved as .wav files.
The price on the Toolbox is $600US. The Flame is $400US. You'll get more mileage out of the Toolbox as it's a full sequencer with LFOs, gates, pitch, etc.
I would check out both modules before making a decision. I own the Toolbox and have used it in such a manner.
