A Sonic Pi script (spi-ctl-bpf.rb) and a Processing one (spi_ctl_bpf.pde) to control a band pass filter using the mouse. Been having performance issues with the sound lagging behind. Setting `set_sched_ahead_time!` in Sonic Pi sounds like it helps, but not enough. Original code from Robin Newman: https://gist.github.com/rbnpi/ca5e80258c0c1296b1c…
