8-voice MIDI rhythmic arpeggiator for norns.
Here’s something I’ve been working on in my spare time. It’s a midi sequencer/arpeggiator kind of thing inspired by the Spitfire Stratus plugin.
Play up to 8 notes on a midi controller, then those notes will be split up and play independent rhythmic sequences that can be sent off to any midi channel. There is some random octave shifting too. Basically, you play some chords, and then it makes it seem like you are playing something much more complex.
It still needs some work, but it’s in a playable state now. This is my first norns script, and it has been super fun to work on.
Play some notes with a MIDI input device and Hopscotch will map each note to its own selectable rhythm sequence. There is a 20% chance that the note will play 1 octave higher or lower when it is triggered. The output can be sent to a variety of devices. If using MIDI out, each of the 8 voices can be sent to any MIDI channel. Voices are assigned in the order that they are played, with each new note taking the first available space.
- MIDI device to input notes
- A supported output device (see below)
You can choose input and output devices in the params menu.
- MIDI out
- Internal norns out with Polyperc (for now)
- Just Friends via Crow (only supports 6 voices)
Use encoder 2 to select which voice you would like to modify. Encoder 3 chooses the sequence.
! option assigns a random sequence to that voice whenever a new note is played.
Note: You must choose MIDI as your output device to see these options
Hold shift (key 1) to swap the sequencer options with MIDI channel options. Select which voice you want to modify with encoder 2, and choose a MIDI channel with encoder 3.
- K1: shift - change midi channel
- K3: hold on/off
- E2: select a parameter
- E3: adjust parameter
- tweak default sequences to be more interesting
get it talking to Just Friends via crow
- use grid to adjust note sequences
