The core
Two generators. Sixteen harmonics each.
Stack them. Detune them. Let them drift into one another until the sound comes alive. Here, harmony isn't picked from a menu : it's sculpted, one slider at a time.
Geranium Production
Something is stirring in the circuit.
An instrument that came from far away. And hasn't finished going further.
Heritage
In the 1970s, a cult additive synthesizer redefined what "harmonic" could mean. Then it left the studios... but never left the memory.
Geranium HARMONIC 75 is certainly not a copy. It grew out of a question: what if it had never stopped evolving?

The core
Stack them. Detune them. Let them drift into one another until the sound comes alive. Here, harmony isn't picked from a menu : it's sculpted, one slider at a time.

The articulation
Envelopes, two LFOs, a matrix of twenty routes and the keyboard under your hands. And one modulator that exists nowhere else : the Harmonic LFO moves the sixteen faders of a generator while the note is still sounding.

The circuit
State variable, Sallen-Key, two transistor ladders, a diode ladder. Four slopes each, low to high pass, set separately for both generators and for the master. Then drive, clock wander and a little crosstalk, if perfection was getting boring.

The lab
Draw a cycle, load one, invert it, normalise it. Then reach for bit resolution, phase behaviour and the Factory 75 experiments. Nothing is fixed and everything can be shaped.

The motion
Thirty-two steps, each of them a note, a tie or a rest, joined by legato bridges that change the pitch without starting the envelope again. Swing and humanisation on top, so repetition never sounds mechanical.

The finish
Chorus, delay and reverb, designed as an extension of the sound engine rather than a plug-in bolted on the end. Dying Tape leans all the way into worn magnetic tape, wow, flutter and dropouts included.
Geranium Production
A harmonic synthesizer. An analog / digital renaissance.
