Note: Pattern Setup
information is saved as it was
set at the moment you saved the
pattern.
Important! You must have
recorded data on the track in
order for the Setup information
to be saved.
In this section the various components of PX-7 sequences are described,
starting from the smallest units "events" and ending with the largest
element, a "song". Songs can be up to 999 bars in length.
Events are the smallest bits of information that are recorded into a
sequencer. Note-on, note-off, continuous controller messages, MIDI clocks,
and program change commands are all events.
Tracks are groups of events that will (by default) be assigned to the same
numbered MIDI channel and will play the preset assigned to that channel.
You should probably stick to using this default setting if you don't need
more than 16 tracks. Any of the 16 tracks can be muted on playback.
PX-7 presets (sounds) are completely separate from the sequencer tracks. If
you change the sound of a preset, it will sound different for all tracks that
use that preset. If you want to customize a factory sound, save it to a user
location and use the new preset in your sequence.
Tracks may also contain multiple MIDI channels. This feature allows the
PX-7 sequencer to control up to 64 different channels at once. There are 32
internal MIDI channels (1A-16A, 1B-16B), and two assignable MIDI ports,
each of which can carry 16 external MIDI channels. A track can be assigned
to play: internal sounds only, external sounds only (MIDI), both internal
and external, or not assigned at all. See page 92.
Multichannel track events can be programmed to play on their assigned
MIDI channels or can be "rechannelized" to a play on a single channel. See
page 92.
Patterns are collections of tracks and are the basic unit of storage for
sequences. You cannot save a track unless it is part of a pattern.
Patterns can be up to 32 bars in length. After playing to the end of its
specified length, a pattern will loop back to the start. Looping repeats
indefinitely as long as the sequencer is running.
Patterns store the following information in non-volatile Flash memory,
which is recalled immediately before the pattern is played.
• Pattern Name & Number
• Track Events
• Initial Tempo & Meter
• Master FX setup
• Track to MIDI Channel mapping ..........
• Track Mutes ............................................
• Bank/Program changes ..........................
• Volume & Pan settings...........................
• Mix Output setup...................................
• Arp Status (off, on, preset, master) ........
