Joranalogue Morph 4
Four-channel morphing VCA and modulation hub
20 HP Eurorack module
Morph 4 is a four-channel voltage controlled amplifier module with a master morph parameter that creates triangular response curves for each channel. It serves as a modulation hub that can crossfade, mix, scan, and shape signals with comprehensive CV control over position, span, and level for each channel.
Features
- Four linear VCAs with triangular morph responses
- Master morph control with CV input
- Input normalization (A→B→C→D)
- Multiple mix outputs (A+B, C+D, Add, Average)
- Min/Max analyzer outputs
- Position and span CV control per channel
- Visual feedback LEDs for levels and outputs
- +5V normal on input A
