How is SHORT working?

It is necessary to use a SHORT ready patch, recorded in the memory of the Circuit as any patch.

The peculiarity of this ready patch is that macro controls have no destination. When you turn them, it has no impact on the synth engine.

On the other hand, they always send CC messages corresponding to their position.

SHORT retrieves these CC messages and translates them according to the page enabled on SHORT and sends it back to the Circuit.

You can access the synth engine parameters by navigating on SHORT's pages, and modify sound using macro controls.

For example, when you are on the filter page, macro 1 control the filter, whereas when you are on the Osc 1 page, macro 1 control the osc1 waveform.

You can edit all the parameters of the synth engine, including 10 matrix, reverb and delay, analog filter and more.

When you find an interesting sound, just record it on Circuit and your sound is memorized.

If you want to use a sound created with SHORT in another session, there are two ways to do that: you can copy the session and erase only the patterns, or you can save the patch with the editor on computer.

SHORT picks up macro controls signal only when you are on the synth 1 or synth 2 pages on Circuit. You can use Circuit normally, on other use of macros, like for drum, mixer or effects.

What about automations on macros controls ?

Because one of the advantages of the circuit is to record automations on the macros, we have planned a favs page.

In this page you find 8 parameters that you have chosen and you can record automations as you would with a classic patch.

Inconvenient compared to the classic use of the macros control, you manage only one parameter per macro instead of 4 usually, but you have access to all parameters including the oscillators waveform, the type of distortion, the lfo waveform, the reverb decay etc.

SHORT's mode:

We have provided several modes of operation allowing you to edit synth 1 or synth 2 or both.

You edit one synth at a time.

Mode 1: you edit synth 1 and you use a classic patch for synth 2

Mode 2: You edit synth 1 and you also want to edit synth 2. while you edit synth 1, the automations saved for synth 2 are returned to the favorites pages.

Mode 3 and Mode 4 are the opposite of Mode 1 and 2:

Mode 3: you edit synth 2 and you use a classic patch for synth 1

Mode 4: You edit synth 2 and you also want to edit synth 1. while you are editing synth 2, the automations saved for synth 1 are returned to the favorites pages.

SHORT and Circuit on your setup.

SHORT is plugged into Circuit's MIDI in and out.

So if you want to send clock, or control another gear with Circuit, we have integrated in SHORT a midi thru which replicates Circuit's midi out.


SHORT works with 1.6 version of Circuit and earlier.

We encourage you to wait for our compatibility tests before switching to a new update.

BLL declines any responsibility in case of incompatibility of SHORT with Circuit in case of future update after 1.6.
