will the a110-4 have linear fm inputs??

i like the a110's in my system, but what i really miss its a linear fm inputs in them.(yes, i do know, it can be added as a DIY panel...)

Right, there is a discrepancy for the traditional frequency control

behaviour for LFOs and VCOs (provided that only one frequency control is

available, but not a set of e.g. fine tune, coarse tune, octave switches).

Usually the controls of a LFO cover a range of several octaves whereas the

frequency control of a VCO should cover a smaller range as the pitch of a

VCO is mainly controlled by a CV coming from the sequencer, keyboard,  Midi

interface or whatever. We added a jumper for the control range of each knob

to pcb. As already said the A-143-4 is planned in the first place as a VCLFO

that can be "abused" as a VCO too. The planned A-110-4 will be more VCOish

(with octave switches, smaller control range of the manual frequency knob,

sawtooth core, PWM).
