NOW UPDATED TO INCLUDE CONTROL OF THE BACKGROUND PULSE AND SCREEEN BOTH PROGRAM AND TOUCHOSC TEMPLATE CHANGED

USE SPloopController4.rb for SP versions 3.31, or 4 or greater. YOu can use the new version of TouchOSC see later in the ReadMe file. A SEPARATE VERSION TUNED FOR Pi3 IS ALSO INCLUDED The original question was concerned with using mekey-makey as the "switch input" source. Here I have used a TouchOSC template with 11 pushbuttons on it as the input source. To make it more interesting, I also drive a large "LED" on the TouchOSC screen with OSC commands from the Sonic Pi program. The program has been streamlined to use just ONE live loop to detect the switches being pushed,

UPDATED NOVEMBER 13th 2022 for new format OSC message parsing introduced in Sonic Pi Feb 2020 Use the file Sequencer2.0-RF.rb for Sonic Pi >= 3.2. which uses the new format

The index.xml file will still work, but once you hav it loaded you may like to amend the top label to Sonic Pi Sequencer 2 by Robin Newman, but this is purely cosmetic and not essential

For convenience I have added 4 specimen json files seq1.json to seq4.json which you can use. You can generate your own otherwise using the write commands in the interface. The location of these files is specified in the program. Adjust to suit your own requirements.

Tuning Sonic Pi for best performance

Several of the programs I write for Sonic Pi push it fairly close to the limit when run on a Raspberry Pi. This note gives some tips on to how to maximise the performance on that platform. Of course, if you run Sonic Pi on Mac OSX,or a Windows PC then the performance is much better on these more powerful platforms and some of the issues may not arise.

Over-clocking your Pi

By increasing the voltage applied to the Pi processor, and running it at a higher clock frequency than normal it is possible to achive significant gains in performance. The down side is that you may reduce the lifetime of your Pi. There are five levels that can be configured: None, Modest, Medium, High and Turbo. I routinely run my Raspberry Pis with Medium Overclocking and have noticed no ill effects on any of them.

If you wish to apply some over-clocking you do so by running the program raspi-config from the command line. Having logged on, from the command line before you start the gra
