Members Awake77 Posted July 13, 2006 Author Members Share Posted July 13, 2006 DonSolaris, I stand corrected...the AX's LFO does indeed trigger with every keypress. I dont know what I heard this morning, maybe just the cutoff changing with varying velocities? Either way, I still dig it. If that's the effect you're after you can 'sorta' fake it by modifying the cutoff manually with the control knob while a sequence plays. Cant record that control data via MIDI though Anyway... Look into the lights, DonSolaris... I want an AX-80, the LFO reset on keypress does not bother me... Link to comment Share on other sites More sharing options...

Members mrcpro Posted July 13, 2006 Members Share Posted July 13, 2006 LFOs that reset with every keypress (usually called LFO key sync) has it's uses but it's always best as an option to free-running. Link to comment Share on other sites More sharing options...

Members Awake77 Posted July 13, 2006 Author Members Share Posted July 13, 2006 Yeah, thats the page I quoted from in the post above. Its a good review. You can get a used AX-80 used for ~$200-$300 in decent shape. A couple effects pedals and this synth sound killer...it is missing some important functionality (like portamento, noise osc, etc) but what it does it does well. Still, not as cool as an Andromeda.

Members ChipCurtis Posted July 13, 2006 Members Share Posted July 13, 2006 Originally posted by Don Solaris I know all other synths from that era have free LFO's: Juno 60, 106, Jupiter 6, Ensoniq ESQ, SQ-80, Matrix 6 etc ... Well, the point I was trying to make is that free-running LFOs (by default) were getting harder and harder to find as we progress further into the mid/late 80s. The Ensoniqs and M6 were probably exceptions rather than the rule. Originally posted by Don Solaris How so? LFO is just an oscillator. You can run it free, or you can reset its phase with each key strike. No big magic here... A DCO is an oscillator too, but how many DCO synths have "free running DCOs" - there's no such thing AFAIK. The waveform cycle always begins at key trigger. They's have to implement separate timing curcuits to have a digital LFO be free-running, would they not?

I always thought that at the heart of a DCO is an analog oscillator whose frequency is determined by a table of values rather than voltages. I'm not sure why it could not be free-running, but I have no technical info or even a DCO synth to check. It's pretty easy to hear if anyone cares to check their DCO synth. Just select two identical waves at the same frequency with a gated VCA and press a key. Link to comment Share on other sites More sharing options...

I'm not sure why it could not be free-running, but I have no technical info or even a DCO synth to check. To my knowledge, a conventional DCO (as in Junos, JX's) is an analog oscillator whose frequency is "clocked by a digital circuit". Your describe as "table of values" - not sure if we are talking about the same thing. AFAIK, a digital circuit just emits square waves as pulses, and the osc freq is determined by that. Originally posted by mrcpro It's pretty easy to hear if anyone cares to check their DCO synth. Just select two identical waves at the same frequency with a gated VCA and press a key. I don't know of any DCO synths that use VCA gate. The conventional DCO does not require a gate. A note sounds off when a keypress initiates the digital circuit, which in turn always starts the osc off at the same point in the wavecycle. That is why you don't get free-running DCOs.

Actually I was thinking in terms of a Juno 60, which has "VCA" labelled on it's front panel, and has a gate option. But I'm really dumb when it comes to the technical details so I'm not about to start an arguement. And that wasn't my point anyway. All I was trying to say is that you can easily hear it if two oscillators are set to the same waveform and frequency and start at the same point in their duty cycle. Especially if they're tuned low. This is the typical sound of a rompler with identical waveforms selected. And I was inviting someone with a two DCO per voice synth to check. And I still am.

Members fugoo Posted July 13, 2006 Members Share Posted July 13, 2006 hey, for what it's worth, I recently picked up a refurb (sealed box) A6 from NovaMusik.com. It took like 3 weeks to arrive but is perfectly 'new' and factory sealed. it's not the 'best price' you'll find on ebay, but it is the lowest 'new' price i could find (save for the sketchy and tariff filled import market taking advantage of our crappy US$) http://www.novamusik.com/search.aspx?type=Model&keyword=1629 hope this helps, fugoo Link to comment Share on other sites More sharing options...

I am not into getting in a pissing contest either on tech details, this is just what I know about DCOs. Just because a synth has a VCA has nothing to do with whether VCA gate is used to sound a note (on a free-running osc), or a digital circuit is used instead as on most DCO synths. Originally posted by mrcpro All I was trying to say is that you can easily hear it if [.........] I'm still at a loss.... what's exactly the "it" that you are listening for? Beating osc's? If two DCOs are set at the same exact freq and they start at the same point of the waveform cycle, isn't that proving my point, not yours? You are the one that is making the case that some DCO synths have free-running osc's, no? still confused here... Link to comment Share on other sites More sharing options...
Members The Real MC Posted July 13, 2006 Members Share Posted July 13, 2006 There is no analog oscillator in a DCO - it is a digital waveform generated by a cpu, not a cap charging core. The waveform cycle always resets on a voice trigger, thus DCOs can't have a "free running" mode. Not counting softsynths/VAs of course. Link to comment Share on other sites More sharing options...

Sounds like you're talking about a digital oscillator (i.e. DW8000, ESQ1, etc), not a DCO (Juno, JX, M6...). In the latter, the "voice" is most certainly analog, the tuning is digital. Originally posted by The Real MC The waveform cycle always resets on a voice trigger, thus DCOs can't have a "free running" mode. Not counting softsynths/VAs of course. Yes I agree here, and that supports my point(s) made earlier. Hence, also supports my point with Don Solaris about why most mid-80s DCO synths also have re-triggering LFOs, not free-running.

Members Awake77 Posted July 13, 2006 Author Members Share Posted July 13, 2006 So the HC seller with the $990 Andy is in the UK (but listing his Andromeda for sale in USD), and only wants $40 to ship it to the US.
