On the original KR-55A and KR-55B, the drum voices were fixed and non-editable. Cherry Audio's KR-55C offers useful parameters that allow subtle or sometimes extreme modification of the stock sounds.
Voice Edit Parameters
The voice edit parameters are very similar for all instruments - enough that we won't individually explain them for each instrument. Suffice to say, they're implemented a little differently with the modeling synthesis under the hood, but we did our best to choose useful parameters. All of the instruments are analog-modeled, which offers far more flexibility for voice editing.
Beginning at the bottom:
Decay- Sets the amount of time for the voice to fade to silence. For the hi-hat, Decay affects the open hi-hat sound only (hence the Open Decay panel label).
Inverted Triangle Menu- This is easy to miss, but these are the upside-down triangles to the left of the Decay knobs. These access a few useful functions.
MIDI Learn Note - <instrument name>- This enables custom MIDI note assignment. To assign a MIDI note, select the MIDI Learn Note menu; the white arrow begins to flash. Strike the MIDI key or button you'd like to assign. The arrows stops flashing and the note is assigned. Custom note assignments are saved per patch - they are not a global for all patches.
<instrument name> MIDI Note- This displays a list of all MIDI notes with the currently assigned note highlighted. The MIDI can be "manually" reassigned by selecting any note from the popup menu.
Reset To Default MIDI Note- Initializes the instrument to its default note setting. Please see the Using KR-55C as a DAW MIDI Sound Module section for more information on default MIDI note assignments.
Reset To Default Sound Settings- Initializes all voice edit sliders back to factory sound preset positions.
Tune- Sets the playback pitch of the instrument. Feel free to dial these to extremes for experimental madness.
Tone- As mentioned, the under-the-hood parameters vary from instrument to instrument, but the general idea is that Tone varies the amount of transient attack vs. instrument body.
Parametric EQ Amount- Sets the amount of the boost or cut for the instrument parametric EQ, with up to 15 dB of boost or cut. Note that the parametric EQ uses a relatively wide bandwidth for more musical tonality, as opposed to a narrow "surgical" sound.
Parametric EQ Frequency- Sets the center frequency of the instrument parametric EQ, from 50 to 12000 Hz.
Trigger LED- These illuminate any time an instrument is triggered.
