12
13 1.0 Introduction
14
15 Itchy is a tiny synth with a big attitude! It's multitimbral and
16 polyphonic, I use it for live performances. It should be pretty stable.

19
20 2.0 Voice overview
21
22 sub
23 A two oscillator subtractive voice with a moog style filter and distortion.
24
25 add
26 A very simple 8 harmonic additive sine synth (works in the drawbar organ kinda
27 way) not very good at present.
28
29 dirt
30 A two oscillator synth with distortion and bit crushing effects for lush lofi
31 sounds.
32
33 fm
34 A frequency modulation (ok, really phase modulation) voice with a few tricks,
35 such as feedback modulation, distortion and hard clipping.
36
37 drum
38 A cheap nasty drumsynth with some inexplicably noisy effects - still under
39 development.

41 --------------------------------------------------------------------------------------
42
43 3.0 OSC interface
44
45 /addinstrument is [ID voicetype]
46 Make a new instrument, assigned to the supplied ID, of the type specified.
47 types can be of the following: "add", "sub", "dirt", "fm", "drum"
48
49 /modify isf [ID token value token value ...]
50 Modify an existing instrument, for example: "/modify 1 "sustain" 2.0 "release" 1.0" see
51 below for a list of all voice parameters (there are quite a lot)...
52
53 /reset i [ID]
54 Reset the instrument to "factory settings"
55
56 /play iiiffffi [timeseconds timefrac ID frequency slidefreq volume pan message]
57 Plays a note at the given time (in ntp format), on the given instrument with
58 the given parameters. if the time is set to 0,0 it will ignore the time and
59 play the note asap. The message parameter is interpreted as a char and if set
60 to a "O" will cause an accent note to be triggered. this will be replaced by
61 something more sane soon :) The slidefrequency gives a frequency to start
62 sliding to (speed is defined by instrument modify commands for voices that
63 support it).
64
65 /setclock
66 Resets the internal clock using gettimeofday() - this needs to be called once
67 at startup.
68
69 /globalvolume f volume
70 The global volume of the whole synth
71
72 --------------------------------------------------------------------------------------
73
74 4.0 Common instrument parameters
75
76 These parameters can be sent to all instruments via the modify message,
77 regardless of instrument type.
78
79 map : Sets the ID that this instrument uses for play messages.
80 poly : The polyphony of this instrument - max is 10 voices
81 mainvolume : The volume of this instrument
82 pan : The pan setting for this instrument
83
84 Common FX:
85
86 crushfreq : bitcrush frequency
87 crushbits : bitcrush bits
88 distort : distortion setting
89 delayfb : delay feedback
90 delay : delay time
91
92 --------------------------------------------------------------------------------------
93
94 5.0 Voice Instrument parameters
95
96 The table below describes the modify tokens that can be sent to each instrument.
97 The range hints are suggestions only, the step really just denotes the
98 difference between integer switches and float controls.
99
100 The type strings take integers to denote the types of different things

234 6.0 Todo
235
236 remove volumea/b -> bias
237 more filters
238 sort out the drumsynth, too slow, bit boring
239 hardclip, distortion, delay, crush on all voices (in Voice.cpp)
240
241 turn off filters if cutoff > 1
242 turn off oscs if volume 0
243 (do we want constant processing time for stability????)
