AJH Synth MiniMod Glide & Noise User Manual

A Noise level :

Sets the output level of the White, Pink and Red Noise. This should be set to +/- 5 Volts

peak to peak, however higher or lower levels can be set if desired by adjusting this

trimmer.

B Glide Scale :

Sets the scaling of the Glide Output, it should be adjusted so that the Output tracks at

exactly 1 Volt per Octave. Note that there is a very slight offset between the Glide Input

and the Glide Output voltage, with the output being of the order of 10 to 25mv lower

than the Input. This is a function of the glide circuit design and can easily be compen-

sated for by adjusting the fine tune of any VCO’s which are connected to the Glide CV

Output.

C Hold Source (J1) :

J1 selects the Hold Source voltage that is normalised to the Hold CV Input if no patch lead is

connected to that Input.
Jumper connected to 1 & 2: Glide effect on at all times
Jumper connected to 2 & 3: Glide / Hold controlled by Gate CV signals on the Eurorack Bus
Jumper removed: Hold effect on at all times, Glide inactive and Output voltage held.

D Hold offset:

FOR MANUFACTURER ADJUSTMENT ONLY. Specialist test equipment is needed to

calibrate this trimmer correctly.

Note:

This information is given for completeness, the MiniMod Glide + Noise module is calibrated

after manufacture and under normal circumstances should not require any user adjustment.
