"Hello hello, here's my second eurorack module øchd or ochd. It's pronounced "oct" as in octave or octuplet and as if by magic there's eight outputs on this module, an octuplet of analogue LFOs if you will. I often find I need more modulation, simple sources that will keep things moving and stop things getting repetitive. That’s why ochd was brought to life, to keep patches organically drifting and moving… and as it’s modular, we wanted an intuitive easy to use module with plenty of patchable tricks up it’s sleeves too!
ochd is a 4HP Eurorack module with eight analogue triangle LFOs. The outputs go from fast on the top output to slow on the bottom output. The default ranges are deliberate NOT synced. These are free running LFOs that were tuned by ear to be musical useful for a range of fast to slow modulations in a patch. Organic animation, drifting and musical phasing is the intention of the module. The rate control controls the rate of all LFOs globally and takes this into lower audio rates right down to 25 minute cycles on the lowest output. This can be extended even slower with CV, with the CV input and attenuverter on board and we can also track and hold the outputs with a negative CV, interrupting and holding modulation values with external gates of CVs. Another trick to take this from simple triangle shapes is to patch a spare output into the CV input and wave shape with feedback. Exponential curves, odd squares, stepped waveforms and more are available with some adjustment of the attenuverter and using different outputs to voltage control itself.
While patching a prototype at DivKid HQ Richard Devine said this was "the most organic little modulator ever" - lovely stuff!"
