Arp3.1 explained

[BeFrankly]

Dear Amalgameated Harmonics, I'm a newbie in building modular synth and found the software Cardinal. I thing you know it. Within Cardinal your modules are available and I tried your Arp3.1. In Cardinal Host Midi Module is set to polyphonic (3 channels) But I did not get any sound out of your module. Your documentation does not help or is not understandable for me. My setup was as follows: Host MIDI V/Oct out to Arp3.1 V/Oct in. Cardinal Host Time Bar out to Arp3.1 clock in. Arp3.1 out to Host Audio. Cala was running in the background and Jack Server has transport started.

So what is wrong with the wiring?

Regards Frank

Hi,

The module does not produce sound, it produces pitches. As an arpeggiator, it takes in a set of input pitches (polyphonic input = V/OCT), a clock signal (CLOCK, for example, a square wave LFO will do). The module will cycle through the pitches, based on the pattern defined at the top (ARPEGGIO), so Straight-R(Right - imagine the pitches written down in order, left to right). The pitches will be outputted, left to right in order through the V/OCT output

I put a screenshot of simple patch that might help

There is a set of pitches coming from PolyVolt, a clock signal from Generative, and this drives the ascending pitch sequence which you will see in PolyScope (the odd step in the middle is due to the screen refresh). The OUT signal needs to go into a VCO (the frequency input, V/OCT). From there is a more usual VCO/Envelope/VCA/Filter setup is used. Since you are using a DAW, the gate could come from the Host module, but there's all sorts of options.
