Appendix D - Midi Implementation - Abstrakt Instruments Avalon Reference Manual

2 STEP BUTTONS
The Avalon has several pattern write modes as detailed in sections 5.2 - 5.5. All of these pattern write modes make use of the STEP BUTTONS. This is
a major addition to the traditional TB-303 style step sequencer, as these button indicators are used for parameter entry and visual feedback. The
STEP BUTTONS correspond 1-to-1 with the pattern steps.
In PITCH ENTRY MODE, when a pitch is entered, the step advances automatically like the TB-303. In addition, the STEP BUTTONS also show the
current pattern step as it automatically advances.
In TIME ENTRY MODE, when a time attribute is entered, the step advances automatically. In addition, the STEP BUTTONS also show the current
pattern step as it automatically advances. The pattern step advances regardless of whether the time attribute is a note event, tie, or rest.
3 WHERE IS TAP MODE?
TAP MODE is an alternative method in the TB-303 for programming time steps by playing time steps realtime while the sequencer is running. TAP
MODE is superseded by RECORD MODE in the Avalon. RECORD MODE allows both pitch and time information to be programmed realtime via the
control surface or from an external MIDI device.
