Experiments with new features

Creations & Ideas

I’ve been playing with a couple of modifications written by @Emlyn and added to the 3.2dev github site. The first gives greater flexibility with the degree function and the second modifies the :piano synth allowing micro tuning ie it can respond to play 72.3 for example.
I put together the following piece. NB THIS WILL ONLY WORK ON 3.2DEV compiled after commit #5a15b84

#Arpeggio Meander by Robin Newman
#an experimental piece using the updated degree function (by Emlyn)
#and also his modified piano synth allowing fractional tuning
#I used a function to generate a honky tonk piano (also applied to pluck synth):beep
#This program required 3.2dev > commit #5a15b84 on May 17th 2019
