!Description
|-
|-
|bowpressurebaseline
|bowpressurebaseline
|
|bpb
|
|[pressure (0 - 65535)]
|
|Sets the ''pressure baseline'' value, scaled by the ''bowpressurepositionengage'' and ''bowpressurepositionmax'' parameters. The ''pressure baseline'' and ''pressure modifier'' forms the total ''pressure position''.
|-
|bowpressuremodifier
|bpm
|[pressure (0 - 65535)]
|Sets the ''pressure modifier'' value, scaled by the ''bowpressurepositionengage'' and ''bowpressurepositionmax'' parameters. The ''pressure baseline'' and ''pressure modifier'' forms the total ''pressure position''.
|-
|bowpressurerest
|bpr
|<nowiki>[conditional (0|1)]</nowiki>
|Puts the bow pressure in the ''rest position''
|-
|bowpressureengage
|bpe
|<nowiki>[conditional (0|1)]</nowiki>
|Puts the bow pressure in the ''engage position''
|-
|bowpressurepositionmax
|bppx
|[value (0 - 65535)]
|Sets the maximum <u>hardware</u> position of the ''bowing jack''
|-
|bowpressurepositionengage
|bppe
|[value (0 - 65535)]
|Sets the ''engage'' ''position'' <u>hardware</u> position of the ''bowing jack''
|-
|bowpressurepositionrest
|bppr
|[value (0 - 65535)]
|Sets the ''rest position'' <u>hardware</u> position of the ''bowing jack''
|-
|bowpressureengagespeed
|bpes
|[speed (0 - 100)]
|Sets the speed of the ''pressure motor'' in RPM when going from ''rest'' to ''engage'' or vice versa. Setting this value too high will result in the ''pressure motor'' loosing track and the instrument malfunctioning as a result. Setting this value too low will result in the instrument getting increased ''latency'' and feeling sluggish.
|-
|bowpressuremodulationspeed
|bpms
|[speed (0.1 - ''bpes'')]
|Sets the speed of the ''pressure motor'' in RPM when at ''engage'' and modulating the pressure. The main purpose of this setting is to avoid the ''bowing motor'' slowing down too much when modulating the ''pressure'', resulting in audible artifacts
|-
|bowpressurehold
|bph
|<nowiki>[(0|1)]</nowiki>
|Sets ''bow hold'' off or on. If ''bow hold'' is on, any ''bowpressurerest''-command will be ignored until ''bowpressurehold'' is set to off. Analog to the concept of ''infinite sustain''

|-
|solenoidengage
|se
|[force (0 - 65535)]
|Engages the ''current solenoid'' with the ''force'' given, the ''force'' is mutiplied by the ''force multiplier'' as set by ''solenoidforcemultiplier''. The ''force'' is scaled according to the ''solenoidmaxforce'' and ''solenoidminforce'' parameters, a ''force'' of ''0'' always means to not engage. Also see ''solenoidengageduration''
|-
|solenoiddisengage
|sd
|<nowiki>[conditional (0|1)]</nowiki>
|Disengages the ''solenoid''
|-
|solenoidmaxforce
|sxf

|Sets the maximum hardware force used
|-
|solenoidminforce
|sif
|[value (0 - 65535)]
|Sets the minimum hardware force used
|-
|solenoidforcemultiplier
|sfm
|[value (0 - 1)]
|Sets the value of the ''force multiplier''
|-
|solenoidengageduration
|sed
|[duration (0 - 65535)]
|Sets the duration of the ''solenoid engagement'' in ɥS. if a value of ''0'' is set the ''solenoid'' will not disengage until a ''solenoiddisengage-''command has been given. This latter behavior is <u>not encouraged</u> as it <u>'''can ruin the instrument if improperly used'''</u>
