An interesting and useful app but….
I can find a lot of use for this app. The octave range needs to be set carefully so each letter gives you a note on a particular instrument - the note range of the instrument needs to be taken into account. For me, setting the rate accurately was difficult and time consuming until I set the knob control to horizontal and vertical. Being able to randomise the rate would be very useful. The gate randomisation needs to be used carefully or you are left with a piece with what seems like too many rests and too little flow.
