Heya Brian, Yes the Avalon does have CV and gate output from its internal sequencer. I plugged it into one of the SEMs I happened to have lying around and its CV out also can't output the highest note. I'll be able to check the actual voltage coming out of it with a multimeter this evening after work, mine is currently hidden in a box somewhere under five hundred other boxes as I just moved house. :/ -Stephen On 14 February 2018 at 01:15, Brian Willoughby <xxxxxx@xxxxxxxxxxxx.xxx> wr= ote: > Does the Avalon have CV output from its internal sequencer? > > If so, measure the CV output to see if it matches the TB303 output or if = the Avalon CV generator is limited. You could either use a Volt meter or ju= st plug it into a known, good VCO (other than the Avalon, which is clearly = suspect). > > My untested hunch is that the Avalon VCO is totally analog and can handle= the high CV and reproduce the pitch, but the internal CV generation can=E2= =80=99t actually recreate the same voltages that the TB303 is generating. N= ot sure why unless it=E2=80=99s going above 5 V, which is a typical limit f= or a DAC without calibrated gain. A VCO wouldn=E2=80=99t necessarily have a= 5 V limit on its 1V/oct CV input, especially not if it=E2=80=99s running o= n +/-10 V or higher rails. > > Brian > > > On Feb 13, 2018, at 1:33 PM, skkatter <xxxxxxxx@xxxxx.xxx> wrote: >> TB303 and TT303 can play the highest C transposed up fine with their >> internal sequencers, Avalon cannot, however Avalon *can* play the note >> when you bypass it's internal sequencer and play it via CV/Gate from >> the TB303.
