Moinmoin Mark,
let me first correct a minor thing regarding my last post:
"Clock Divide" still works when P'08 is set to external MIDI clock, but "BPM" is out of effect.
If You set the P'08 as a MIDI clock slave (by setting MIDI clock to "MIDI In" in the global settings menu [P'08 user manual page 8]), it will stop generating and therefore neither care for nor send its internal MIDI clock signals.
If You set the P'08 MIDI clock setting to "MIDI In/Out", it will behave the same, but in addition "forward" the received MIDI clock signals to its MIDI out and Polychain outputs.
I do not know whether I completely understand what You are doing and where You change parameters, but hereafter assume, that You did set Your P'08 to "MIDI In" or "MIDI In/out".
Please bear in mind, that the latter may create a MIDI feedback, if You set Your Logic to accept external MIDI clock signals!
If You send note on commands or change parameters within Logic, these will of course influence the P'08:
- every clock signal (change) sent by Logic will change the P'08 timing
- every "note on" sent by Logic may newly trigger the P'08 sequencer, if You allow for it [P'08 user manual page 29, "Sequencer Trigger Modes"]
- every "note on" sent by Logic may newly latch / add notes to the arpeggiator, if You allow for it [P'08 user manual page 31, "Arpeggiator"]
You should know, what Logic sends and how P'08 reacts on it, so
- take time to experiment with "simple" commands, before You try complex command sequences and
- try all MIDI parameters sent from Logic to P'08 individually before applying combinations, in order to learn, what is influenced by what and how.
There will surely be some kind of "MIDI command log" at the Logic side, where You can see, which MIDI commands are sent and/or rerceived by Logic. You will be able to investigate the behaviour of Your MIDI equipment by looking at these logs.
So set Logic and P'08 MIDI settings to Your needs and try to tweak parameters at the P'08 side:
Are there MIDI-clock commands received by Logic from P'08?
If so and P'08 MIDI clock setting is set to "MIDI In", there is definitely a fault at the P08 side. Honestly I consider this as very unlikely, but who knows...
Is there a specific setting I need to look at to apply the above behaviour?
Nothing except P'08 MIDI clock set to "MIDI/IN" or "MIDI IN/Out" as described above
Do you use midi clock In / Out because you're using the poly out?
I only use Polychain output as an extra MIDI out [P'08 user manual page 7] and want to have the external clock not only for P'08 and those MIDI-devices connected to P'08 MIDI through, but also for those connected to P'08 MIDI out (and Polychain, which is a second MIDI out). The reason for this wish / requirement will be found as answer to Your next question:
Can I ask separately (maybe related) what the benefit of a clock pedal is?
And how flexible would it be in relation to the rest of my setup?
I've got a couple of other synths, maschine, TR8, a linndrum, MS20..
Can it all be synced to the clock pedal?
For me the main benefit of MIDI clock pedal is the classical "tap tempo application":
I can adjust all preprogrammed tempos on the fly, which is very important for me as a live and combo player at rehearsals and on stage.
When in studio there may be a "click", which also usually is available as MIDI clock, so I simply have to replace the clock pedal by this "general time signature"If You want to sync MIDI tempo between all Your equipment (or even with equipment of Your bandmates, like e.g. echo rates of different player's instruments), You will distribute the MIDI clock signals to all relevant MIDI equipment. Just use the standard MIDI out and through facilities.
In Your case I can imagine a P'08 sequence, arpeggio, or filter sweep perfectly in time with the groove of Your linndrum or other equipment.
Whether all of Your equipment is able to receive (and react on!) MIDI clock will be stated in the regarding user manuals resp. their MIDI implementation charts.
HTH
