value received. The range of this field is 0 - 127, with 127 being the full range

of the controller. (Pitch bend is an exception- even though the pitch bend

messages actually have a range of ± 8191, 0 to 127 represents the full range

here. For example, to specify that only a change of 10% or more in the total

range of the bend wheel may be recorded, enter a 12 here, because 12 is

approximately 10% of 127, which here represents the full range of the bend

wheel.) If this value is set too high, a definite "step" effect will be heard as

the continuous controller is moved. If you want a continuous controller

effect, try to pick a value which is low enough so that the "stepping" is not

noticeable. Of course, you may wish to implement this "stepped" effect in

order to generate glissando-like effects.

• The VELOCITY MODE and FIXED VELOCITY fields: Incoming midi

note events are normally recorded into the sequence with their velocity

values intact, permitting the recording of dynamics. These two fields permit

the incoming velocity data to be ignored, if desired, and a fixed value

substituted for each incoming note. The VELOCITY MODE field has two

options: NORMAL and FIXED. If set to FIXED, all incoming velocity

values are replaced by the value specified in the FIXED VELOCITY field (1

- 127).

The OTHER MIDI section:

• The MIDI SOFT THRU field: If set to ON, any incoming Midi data is

routed in real time to the selected track's output Midi channel. If set to OFF,

it isn't. If you are using a single keyboard synthesizer (the keyboard and

sound generator are together in one unit), this field should be set to OFF. In

this case, there is no need for incoming midi notes to be immediately sent

out to the synthesizer's sound generator because it is already receiving notes

directly from its keyboard. If you are using a midi master keyboard and

separate synthesizer modules, set this field to ON. This way, the notes

played on the keyboard will play the synthesizer modules in real time.

NOTE: When MIDI THRU is set to ON, be careful to avoid a midi

"feedback" loop in your external midi cables and devices. A midi feedback

loop occurs when an output midi message, because of some incorrect

external midi connection, is immediately sent back to the input, then it is

immediately sent back out (because MIDI THRU is ON), then back in, then

back out, etc. If this occurs, the MPC60 could "freeze" until one of the midi

cables is disconnected. To avoid this, be very careful in connecting your

external midi cables and devices to prevent a direct signal path from the

MPC60's midi output to its midi input.
