Vintage B3 Percussion options in Logic Pro for iPad
Vintage B3 emulates the (Key) Percussion features of the original B3. The Percussion function is available only for the upper manual. The effect adds the second or third harmonics to the attack envelope of a note. These harmonics quickly fade out, leaving the chosen draw bar tones.
The Percussion effect is polyphonic, but is only (re)triggered after all keys have been released. If you release all keys, new notes or chords sound with percussion. If you play legato, or sustain other notes on the upper manual, no percussion is heard.
Important: Percussion controls are spread across two interface sections: Percussion and Percussion Options.
Percussion Options parameters
Percussion Polyphonic buttons: Determine the percussion effect behavior.
Mono: Enable to trigger a mono percussion effect with each key press.
Para: Enable to trigger a polyphonic percussion effect. Each played note in a chord triggers the effect.
Poly: Enable to engage a polyphonic percussion effect that only (re)triggers after all keys are released. If you release all keys, new notes or chords sound with percussion. If you play legato or sustain other notes on the upper manual, no percussion is heard.
Percussion Mode switch: Set to Only B to simulate the B preset key restriction. Choose Always if you want percussion to always be available. See Use Vintage B3 preset keys.
Perc Slow/Fast knobs and fields: Set independent percussion decay times for the slow and fast Time switch settings. No percussion decay occurs when Perc Slow is set to maximum.
Perc Time knob and field: Set an overall decay time that scales the Perc Slow/Fast knob values.
Perc Soft/Normal knobs and fields: Set independent low (Soft) and high (Normal) levels for the low and high Perc Volume switch settings. This is an improvement from the B3, where Time and Volume could only be turned on or off.
Perc Level knob and field: Set an overall percussion level that scales the Perc Soft/Normal knob values.
Upper Level knob and field: Set the balance between the upper (percussive) manual and the lower manual/pedals. On the B3, percussion is available only if the B preset key is selected. See Use Vintage B3 preset keys.
Perc Velocity knob and field: Set the percussion velocity sensitivity (unlike the original B3, which is not velocity sensitive). Engaging percussion on a B3 slightly reduces the volume of the normal, nonpercussive registers.
