Pulse Wave
The pulse wave is slightly more complicated, because it is not one waveform, it is many different ones.
A pulse wave is a waveform that during one period jumps once between full positive amplitude and full
negative and then back.The thing that can be varied is where within the period you jump from maximum
to minimum amplitude. Let’s look at three examples:

- The amplifier 86
- As described above the envelope stays at the sustain level until the key is released it then falls back to zero level the time it should take for this to happen is set with the release parameter which works just as the decay only it is not applied until you lift your finger off the keys 88
- M if you set sustain to 0 the sound will become silent after the decay phase is finished with short attacks moderate decay times this can be used to simulate the behaviour of a plucked string instrument guitar piano etc where the sound always decays to silence after a while 88
- M if you set sustain to full level the decay setting is of no importance since the volume of the sound is never lowered 88

- In the patch and performance dump messages the data bytes contain the actual patch performance set tings 98
- M a patch contains 66 parameters which means the data block of a patch dump is transmitted in 132 66 2 bytes see the patch dump format table below 98
- M a performance consists of five blocks the first four blocks contains the four patches a to d this block is 528 midi bytes 4 66 2 after this follows 136 68 2 of data for parameters local to the performance see the performance data format table on page 97 98
- M all parameters are in 8 bit format 2s complement signed each byte is nybbleized and coded into two midi bytes with the low nybble transmitted first 98
