Instrument

Every instrument has one Instrument module.

Parameter Description
Name Instrument name.
Blob Number The blob number to use when exporting the instrument to use in a GE-based product can be set here. Set to ‘-‘ to include a custom blob name in the Blob Path.
Blob Path Folder to save the .blob file (path should be relative to the instrument location).
Volume Volume for the whole instrument (leave at 0.0 dB to minimize CPU load). Often this parameter will be controlled by the instrument script to implement the master volume.
Tune Tuning for the whole instrument - note this is tuning of all samples, not transposition of the MIDI input.
Output Selects the main audio output - normally leave this set to 1.
Voices Displays the current number of voices the instrument is playing.
Sustain Pedal Sets the sustain pedal mode. Possible values are:
Off: No response to sustain pedal, so it can be handled in the instrument script.
On: Normal response to sustain pedal.
Latch: Sustain notes until the next note is played.
Damper: Sustained voices are not released while the sustain pedal is held, or the key that triggered the voice has been played again and is still held.
Glide Only has an effect in Group modules where the Glide mod source is used. Possible values are:
Off: No glide.
On: Always glide.
Auto: Only glide if a key is already held.
Default Keyswitch Sets which keyswitch key (if any) will be active when the instrument is loaded.
Pitch Bend Range Adjust maximum depth of all modulation routings from Pitch Bend to Group Tune.
Active Events Displays the number of script events currently active - useful for script debugging. Hanging events are most likely note events that were never released.
Script Defines List of words separated by spaces or commas, used with script USE_CODE_IF().
Overview Size Number of overview points to generate for samples (applied when exporting). Should be equal or greater than the width in pixels of the waveform display.
Simultaneous Max If set, limits the number of MIDI note and pedal messages in one audio buffer to reduce the maximum CPU load. Excess messages are delayed until the next audio buffer.
Group Solo Displays if any groups are currently soloed.
Bus Solo Displays if any effect busses are currently soloed.
Pitch Mod Range Adjust maximum depth of all modulation routings (except from Pitch Bend) to Group Tune. Warning: Playing samples at extremely high pitches can lead to aliasing, high CPU load, and drop-outs unless the whole sample is in RAM (using Start Mod Range in each Zone).

Scripts Script

Script

Contains the instrument script and displays any parameters declared in the script for editing.

Parameter Description
Bypass Bypass processing of note and controller events by this script.
Script Path Location of script text file on disk.
Script Text of currently active script.
Status Last message printed by the script.

Group

The Instrument can have any number of Group modules. A Group module organizes multiple sample zones and allows for setting trigger conditions and other settings that apply to all samples in the Group. Each Group can contain up to 16 mod sources, 64 mod routings and 16 filters.

Parameter Description
Name Name to display for this Group.
Active When switched off, the Group will not respond to incoming notes.
Volume Volume for all voices in the Group.
Pan Pan (balance if stereo) for all voices in the Group.
Tune Coarse and fine tuning for all voices in the Group.
Tracking Pitch tracking of samples across the keyboard (0% = none, 100% = normal).
Output Select the audio output or Effect Bus to output all Group voices to.
Voice Group Select a Voice Group to control the Group polyphony.
Voices Displays the current number of voices the Group is playing.
Quality Sample playback interpolation mode. Each mode has a different trade-off between CPU load and sound quality. Possible values are:
Eco: Lowest quality and CPU load. Fine for background sounds, or sounds with little high frequency content.
Mid: Middle quality and CPU load. Use instead of Lagrange to increase quality if transposing up a long way.
High: Higher quality and CPU load. Use instead of Sinc 8 to save CPU if transposing up a long way.
Lagrange: Standard 4-point Lagrange interpolation. Good quality for most sounds. Low CPU load.
Hermite: 4-point Hermite interpolation. Similar to Lagrange but sounds smoother at the expense of some aliasing.
Sinc 8: 8-point Sinc interpolation. High quality, but high CPU load especially when transposing up.
Vintage: Emulates a variable rate DAC without an anti-imaging filter (so you might want to add your own lowpass filter tracking the pitch). Low CPU load.
Release Trigger Group should play when a note-off is received rather than a note-on.
Release Timer Used as a mod source for attenuation of release-triggered voices depending on how long the note was held.
Sample Start Adjust the sample start point of all zones in the Group (subject to the zone Start Mod Range setting).
Loop Follows Start Possible values are:
Off: The sample loop set in the Zone is played, unaffected.
On: The sample loop is shifted to the playback start position, which can then be modulated.
Quantized: The loop position is rounded to the nearest multiple of the loop length, so startpoint modulation steps through different sections of the sample for wavetable-style playback. For best results set the sample loop to the last wavetable in the sample and Start Mod Range to maximum.
Quant+Phase: Same as Quantized, but the sample starts playing at a random position within the loop, to avoid unwanted alignment between unison voices.
Mapping Shift This allows the sample mapping to be shifted up or down the keyboard. Usually used in combination with the Tune parameter to transpose the group, compared to just tuning the group which may play samples outside their normal key range.
Alternate Mapping Select an alternative set of sample zones to play, instead of this group’s zones.
De-glitch Start Reduce clicks when the sample startpoint is not at a zero crossing.
Mute Mute the output of this group (unless Solo is on). Does not stop voices in the group from playing.
Solo Solo this group and mute any non-soloed groups. Set to Ignore if soloing other groups should not mute this one.
