The latest loopop video takes a look at the art of MIDI hacking – manipulating MIDI signals in realtime to expand the ways you can use your hardware. Previous loopop videos have used MIDI hacking to play melodies with samples on the Novation Circuit, turn the Korg Electribe 2 into a 3 oscillator synth, add CC to CV functionality to the Arturia BeatStep Pro, all things that can’t be done out of the box with those devices.
With the earlier videos, Lemur scripting was used. This demo looks at using the Bome Box and MIDI Translator Pro to do this sort of live MIDI manipulation.
Here’s what loopop has to say about the video:
This time I decided to see if I could extend the capabilities of Elektron’s Analog Four. The A4 is an amazing synth with four analog voices which can either play different sounds each, play one sound with up to 4 voices polyphonically, or any combination in between.
However, with this “MIDI hack” it can do more.
Each of the A4’s voices has 2 oscillators. Out of the box, you can’t configure these voices to be played separately with the internal keys or an external keyboard. You can manually step sequence each of the oscillators using parameter locking, but that precludes real time play and is hard to do using a tuning knob.
That’s where this short 3 line script saves the day. With it, you can play each of the 4 voices of the A4 paraphonically with a simple keyboard split on an external MIDI keyboard.
Playing paraphonically has a different character than playing two separate notes. Both notes share the same envelope, filter and fx, which is a limitation, but actually gives the music created a unique feel, similar to what can be done on the Moog Sub 37.
With this short script you can potentially turn your A4 to a “paraphonic A8”, by applying this script to all 4 voices.
This should work on the Analog Keys as well, but you would need an external keyboard for that.
