recalling presets interrupts scheduler?

I’m doing some fairly simple step sequencer stuff, sending out midi sequences determined by a couple of matrixctrl objects and a few multisliders, which i can store in a preset object.

when I change sequence by recalling a different preset, the midi output is interrupted, and mistimes for a beat or so.

I’ve tried using pattrstorage, and if anything the glitch is worse.

Any ideas why this is, and how i can avoid it ?

can you post a simple example of what you are experiencing? Do you have Overdrive turned on?

my bad…

simplified the patch and sure enough, preset was flushing some notes that shouldn’t have been flushed…….works fine now

just bought Max 5….the interface is great so far.

actually I still have a problem with this

this patch shows how using midi input to change a preset (that causes a few calculations to occur) causes notes to be output erratically, but using the computer keyboard doesn’t cause an interruption.

i have no idea why this is but its ruining my acid lines.

If I turn Overdrive on it works fine.

Actually – I tell a lie, there does seem to be some kind of difference in performance between using the keyboard and using MIDI.

Perhaps there’s just too much going at high priority. Try putting a defer before the preset object.

works like a charm….
