Sample Chains on MD?

void · 2014-03-03T12:45:30.000Z

here’s the code which does the slicing, which is trivial:

not going to show my code for manipulating sysex at this point… maybe later.

Great, very apprecciate

void · 2014-03-03T13:16:33.000Z

here’s the method which gets called when you press the slice button:

gist.github.com

https://gist.github.com/jpenca/9324621

MDSlicer request

- (void) doIt
{
	[self.sliceApplyButton setEnabled:NO];
	
	int offset = self.firstStepSlider.intValue - 1;
	int length = self.lengthSlider.intValue;
	int skip = self.skipSlider.intValue;
	int sampleLength = self.sampleLengthSlider.intValue;
	float reverseAmt = self.reverseRandAmountSlider.intValue / 1000.0;
	float shuffleAmt = self.shuffleRandAmountSlider.intValue / 1000.0;

There’s a system for asynchronous requests of SysEx data…
In the method above, there’s 2 nested requests.

first i’m asking for the current track number, then getting the current pattern. then apply the slicing and send the pattern back to the MD.

MOKA · 2014-03-03T13:23:38.000Z

Really thank you, a question …
you regenerate the checksum or not when you send the pattern?

void · 2014-03-03T13:25:58.000Z

yes… without correct checksum the MD will not accept the pattern

MOKA · 2014-03-03T13:30:03.000Z

thanks for all the info

void · 2014-03-03T16:07:33.000Z

is there any interest in a thing like this?
wondering if it’s worth putting more work in it.

Accent · 2014-03-03T16:24:06.000Z

Haven’t had a chance to even use it yet, but yes, I’m interested.

FreeFall · 2014-03-03T17:03:40.000Z

Damn VOID, you are so hired!

I haven’t had a chance to play with the MDice app yet (just downloaded it) but I’m excited to play with it. This is a great tool for exploring sections of a loop, without having to do all the tedium of setting START/END points. Very very cool.

It may be a day or three before I can dig into this thing, but I’ll report back once I do.

Thanks VOID!

having good results with Amen-Break autojungle & other drumloops.

but also, short chains of 4 or 8 one-shots work well…
recording a chain via RAM machine, then slice&dice…

i don’t have an OT and am not really familiar with that sample-chain concept, but it works very well… basically storing a mini-drumkit in a sample

what’s cool is that you can pitch the individual hits without messing up timing.
also, you can change the MD master tempo and the sliced stuff stays synced.

void · 2014-03-03T18:38:47.000Z

updated the app with the following functionality:

can now optionally auto-save the current Kit. This is a workaround for the MD-behaviour of reloading the kit when receiving a pattern, so you don’t have to save it manually if you make a tweak.
has an option for locking the pitch-parameter of all generated trigs to the value that’s currently in the kit. this only works when kit-auto-save is enabled.

This is a fantastic idea!

I don’t have Mavericks installed yet, so I can’t give it a shot. I’m seriously considering upgrading just for this.

I can’t wait to try it!

Accent · 2014-03-03T20:06:49.000Z

Damn, must have missed it was only for Mavericks. I’m still on ML and don’t plan to update any time soon, since Live 8 is buggy on 10.9 from what I understand. Bummer. If it is compatible with any previous versions at some point, I’m all in.

void · 2014-03-03T21:43:22.000Z

dunno, there is something in my framework code which seems to make my stuff fail to run on older OSX versions… hard to find out sans an older Mac to properly debug this.

here’s a build which should run on 10.7:

can anyone try? if it fails, can you send me the log?
(open /Applications/Utilities/Console.app, there should be some info in there)

Yes, I’m very interested in this kind of thing. I just downloaded and will get to playing with it in the next few days.
Thanks for taking the time to make it available.

wow, awesome!!

will be trying this and let u know how it goes

Deep_Cycle · 2014-03-04T11:27:04.000Z

Cheers Void

sd88me · 2014-03-11T07:25:05.000Z

got this going! this is awesome!

void · 2016-11-10T15:20:28.175Z

bizzump! Haha totally forgot about this

sicijk · 2016-11-10T15:38:58.324Z

Haven’t ever tried this since I was on 10.6.8 at that period-----now I’m on 10.8.5…any chance this would work?

Thanks a lot
