#X text 229 19 This is an analog-synth sound made using a wavetable
oscillator and a "vcf~' object. Unkike the "floyd" example earlier
\, we use a qlist object to do the sequencing. This can also be adapted
to make a keyboard synth.;
#X text 227 85 The qlist reads the file \, "qlist2.txt" \, which contains
four "note" messages and a message at the end that restarts the qlist
at the beginning. The "note" messages are translated into a pitch change
and triggers for the ADSRs.;
#X text 667 551 updated for Pd version 0.39;
#X text 379 305 ADSR for filter. Here \, it works better to make the
envelope modify a constant "filter pitch"--so the "filter" receive
gets the "mtof" treatment and the ADSR is an offset in halftones.;
