Report Effect Parameters

This message allows external equipment to determine what parameter numbers are associated with a
given effect or controller type and algorithm number. Any MPX 1 effect can have a maximum of 30
parameters, so space is set aside in the message packet for that number of parameters but the actual
number of parameters is passed as the first byte.

Typically, a request for this information is followed by a request for a description of each of the parameters
using the Parameter Description message.
The effect type and algorithm number are the only two parameters used in the request message for this
packet:
Effect Types are defined as follows:
0 Pitch
1 Chorus
2 EQ
3 Mod
4 Reverb
5 Delay
6 Knob
7 LFO 1
8 LFO 2
9 MIDI Arpeggiator
10 ADSR 1
11 ADSR 2
12 Random Number Generator
13 A-B Generator
14 Sample and Hold
15 Envelope Generator 1
16 Envelope Generator 2
Note that, although 6-16 (Knob-Envelope Generator 2) are really not effects, they are handled by the
system as such. From an MIDI editor's perspective, the only difference between these Effects Types and
the audio effects is that these only have a single algorithm: 1. As such, they always have the same
parameters.
