The Tiny-TS is only monophonic and doesn’t have an arpeggiator.
But with the v1.1 firmware it now also handles CV and Gate input from a sequencer to make it play arpeggios.
On startup it checks if the Gate output is grounded.
If it is it reverses the CV/Gate ports to inputs.
The Gate now triggers the envelope and the CV input shifts an octave up on the keyboard.
You can now play arpeggios.
