Subject: Random sample and hold - control parameters - TO DO LIST

I would love to hear this too...

I've added it into the HAWK-800 "to do list".

And just so as you know how much I appreciate this list too, I want to send out a big thanks to all of you (both HAWK customers and ∗potential∗ HAWK customers!).

Without this list, I would not have come up with some of the great features that went into the HAWK. And in fact, the AtomaHawk would NEVER have existed at all (stay tuned for a follow on email about the FM-800 mod').

And it is this kind of discussion that feeds my own development of the HAWK. For example, I have been toying with the MIDI LFO clock sync idea for some time and I haven't been happy with the way the current LFO2 clock MIDI sync operates because it doesn't cycle in perfect time with the MIDI clock (except at the slow speeds it does). But this little exchange got me thinking about that and ∗bingo!∗ I struck upon a solution.

So I am going to add another "to do" to the list that will alter the LFO rate values according to whether MIDI sync is enabled or not. When enabled, the clock rate will use rates that ensure that LFO2 stays in cyclic sync with MIDI. I'll put a better explanation together once I implement it.

The random sample and hold controls as suggested can be done but it will take some time because the LFO's are completely software generated and the number of CPU cycles used to drive all of these new controls taxes the Poly's performance. So it's on the list but implementation may take a bit of time.

Cheers,

Mike
