Members Gaul Posted June 3, 2012 Members Share Posted June 3, 2012 Apart from Yamaha, everybody is apparently silent on this matter. In theory, internal sequencer could take more polyphony at once, than the capacity of internal sound generator, as indicated in the Yamaha MO6 and MOX6 specifications, which means you can connect to them additional sound source(s) (keyboard/module) and make more complex arrangements.On the other hand, polyphony is not the only data that is sent and received from sequencers, which makes the things more complicated... Any interesting experiences to report about such use of sequencer with more than one tone generator? What would be the most friendly keyboard for internal sequencing, apart from MO6 and MOX6?

Members The Audacity Works Posted June 3, 2012 Members Share Posted June 3, 2012 I'm not sure what you mean. Polyphonic aftertouch can be recorded and played back by sequencers (the Yamahas certainly don't generate poly AT), but polyphony has everything to do with the sound engine, not the sequencer. Nearly all modern keyboard sequencers can record and play back way more data than their sound engines can handle, polyphony-wise. The most powerful keyboard-based sequencer is found in the Fantom-G Link to comment Share on other sites More sharing options...
Members Gaul Posted June 3, 2012 Author Members Share Posted June 3, 2012 Yamaha doesn't say anything in their specs regarding their sequencers that the others fail to mention. I noticed that there is nearly always that line "Sequencer polyphony" in Yamaha workstation specifications that regards sequencer capacity. Check their factory page with MO6 or MOX6. Actually, if you look at their old brochures, dating way back to V50 and SY77, there is always mentioned sequencer polyphony. I never ever saw that with any other brand.

Members The Audacity Works Posted June 4, 2012 Members Share Posted June 4, 2012 That's in general what I wanted to know.The question comes from my memory, because I remember having Korg 01W/FD at my disposal with Roland JV-80. Internal sequencer choked quite a few times, and I was not sure was it related to 32/28 polyphony of the instruments or to the underpowered sequencer.It's pretty difficult to choke a sequencer, and very easy to get dropouts with only 32 notes of polyphony.In the meantime I found out that, for example, sequencer in Roland JV-1000 can handle 128 MIDI tracks!The JV-1000's sequencer had 8 tracks. 16 has been the standard for decades. Roland simply went a little crazy with the Fantom-G.I noticed that there is nearly always that line "Sequencer polyphony" in Yamaha workstation specifications that regards sequencer capacity.Sequencer capacity has to do with how many MIDI messages can be stored. Generally, it's in the tens or hundreds of thousands of events range, but again, that has nothing to do with polyphony. If Yamaha's printing a "sequencer polyphony" spec, then they're misusing common terminology. This is my favorite doc for explaining the fundamentals: http://www.midi.org/aboutmidi/intromidi.pdf Link to comment Share on other sites More sharing options...
Members Gaul Posted June 4, 2012 Author Members Share Posted June 4, 2012 If Yamaha's printing a "sequencer polyphony" spec, then they're misusing common terminology. While I understand what you mean, I think that Yamaha's expression "sequencer polyphony" is kind of a shortcut of explaining of what to expect in sequencer use, which I appreciate more than keeping silence and letting the user wonder what to expect in sequencer use with external sound source. In early years, their "sequencer polyphony" just matched the polyphony of internal generator, as indicated in V50 (16 poly) and SY77 (32 poly) specs.

Members evildragon Posted June 4, 2012 Members Share Posted June 4, 2012 It's not the friendliest sequencer tho' Link to comment Share on other sites More sharing options...
Members The Audacity Works Posted June 4, 2012 Members Share Posted June 4, 2012 Eight tracks in JV-1000 are just a surface. I am quoting from JV-1000 manual: "Each phrase track can record song data consisting of MIDI channels 1-16. As long as the MIDI channels are different, the same track can contain independent data for more than one song. Also, since song data is handled independently for each phrase track, even MIDI messages of the same channel can be handled independently, if recorded on different tracks. In this way, although the JV-1000 sequencer may appear to have only 8 tracks, it has the functionality of 128 tracks (8 x 16)."Except that's not what a track means. If it were, then the Fantom-G has 4,352 tracks (128 real tracks x 34 total parts/channels). The JV-1000 had 16 discrete parts and IIRC, there wasn't an elegant way to control external MIDI sound modules separately from internal parts. So, even with their bastardization of the term "track", in practice, the JV-1000 could still only control 16 different instruments. A "track" is a discrete lane to which MIDI data can be recorded, played back, and edited (and quickly muted, soloed, etc.). Roland chooses to allow multiple channels be recorded to a single track Link to comment Share on other sites More sharing options...
