Midi-to-CV/Gate A-190-2

(7) CV Characteristics

With programm change #19 and #20 one can select

between V/Octave and Hz/V characteristics for the CV1

output. Within the A-100 this features is not required

because all VCOs and VCFs use V/Oct only. Only if the

A-190-2 is used to control other equipment this function

might be useful. V/Octave is used by most of the

synthesizer manufacturers (Moog, ARP, Oberheim,

Roland, Sequential Circuits, Doepfer). Because of the non

linear voltage range mode the resolution is very poor in

the Hz/V mode, especially in the lower voltage range.

Consequently the Hz/V mode should be treated as a free

bonus and used only if there is no other solution.

(8) Control change number for CV4

If the A-190-2 receives a Midi control change message

(except bank controllers 0 and 32) while being in the

learn mode the control change number of this message

defines the new control change number for CV4 (except

bank controllers 0 and 32). I.e. the CV4 output of the A-

190-2 corresponds from now on to this controller number.

The control change message must be sent on the A-190-

2 Midi channel (see note 1).

System A-100

Temporary parameter changes

The program change messages listed in the table can be

used to change the settings even temporarily without the

need to select the learn mode. Temporarily means that

the changes are not stored permanently in the non-

volatile parameter memory but only as long as the module

is powered. If the A-190-2 is turned off and on the

previously stored parameter settings are called up again.

The temporary changes may be used to try out different

settings without storing them into the memory or to

change the settings temporarily from a Midi foot-switch or

sequencer (e.g. retrigger on/off for, assign mode change).

If the parameter changes have to be stored permanently

the learn mode has to be used.

All program change messages must be sent on the A-

190-2 Midi channel (see remark 1).
