my custom interface and reaktor patch

[em978]

I have been working in my little hole for awhile with this thing. Almost a year..
The video are the same but in two flavors.

I have two big issues with this reaktor instrument i built
1)reaktor is sending out bunk midi note on data to the lights at points ... and it has to be because it happens on beginnin of the sequence...
2) the grain sampler which is in core audio is destroying all my pitch material... I using the basic two grain .. sin wave cross fading thing..
So i'm wonder if anyone could help me out with these problems????
thanks

Evan that interface/program you have made is awesome.
Thanks for the demo movie.
I am unable to help you out with your questions. Sorry.
That was so cool I'm going to watch it again.
Truly remarkable.

the interface is really great! i want one!!!

;-)

are there any audio switches on your Reaktor ensemble that are being switched on and off?

it is difficult to really know who you are getting these bugs unless
we are there with you (shame i live in the UK, so i can't pop round)
or if we see the ensemble itself.

Well there is some audio switches.. but that wouldn't really effect it since the only thing that is changing the light is midi note out data from reaktor... i'm thinking it might have something to do with the amount of midi note out objects i am using.
thanks for the comments

switches effect all midi data - do a search on swithces in this forum. basically, since a switch re-evaluates the whole signal flow and disables unused portions of the instrument, the whole thing needs to be re-initialized (meaning, all the events). the solution? - either, dont use switches, or take good care of the initialization scheme (R5 now has a "show init order" debug too that is very useful).

[kid_sputnik]

ok, i watched the video - this is really fantastic!

can you describe the problem with the granulator more in-depth? if you want, you can e-mail me as well, its kid_sputnik@yahoo(dot)com, or keep the discussion here if you want so others can learn (i think there are alot of people here who would be super-interested in your setup!).

Ok
Here goes my explation that about the midi out issues.....
First thing the only way the lights on the box are being turned off is from midi note data that is being sent to it directly from Reaktor.
Second i do not have an of my gui being controlled by midi into reaktor from the the box.. (I ran into big problems we i was controlling them this way because the gui would stick when i would hold the buttons down for a long time... the buttons where in gate mode when this happened. bug??) So instead I have midi note incontrollers that look for specific notes that are them sent to midi out to turn the lights on. This set up is only really used for the effect buttons and record buttons. The actually sequence data for the sample slices, is set up in a way that at the end of ensemble, there is an object that is testing to the data coming from the event sequencer (-1 to 7... -1 being note off data) and seeing what number it is and then if it is that note turning gate on for the midi note that the button is assigned for...
The thing that is weried is that effects buttons at times usually defined my the clock will come on and stay on (until i press them ) if i how down the button too long. i got rid of some of these issue by resigning my midi notes on the box to different note values?? The whole thing happens sometimes and then works fine... It might be the hardware but since it seems to sync up with the first beat of the sequencer... I thinking it's an issue with reaktor
One of the issues I'm think is that I have something like 60 midi note objects in my ensembl since,all note notes have there own midi note out object. maybe I can use one with multi-poly?? maybe... The thing I was debating about doing was have a note that flushes all midi data out...
I hope this is clear... the whole patch is huge...

The grain issue.... my grain sampler is pretty much the same as the one that was in that tim exile patch.. two windows using sin wave shapes to crossfade between samples... but when i put it pitch material and it isn't at the right tempo it basically destories it... I think i might need some anti aliasing object... but I'm not sure.. All those exile patches that are flooting around have the same problem too... This grain sampler doesn't have a density control.. but even with that it doesn't seem to work.... I really trying to build ableton's sampler in my reaktor patch... maybe i should buy that curtis roads book microsound, that might help me.

Maybe someone can answer this ... why is my patch 127mb is size with no samples in it???

thanks

what im wondering is, is the granulator working on a lookuyp sampler, or is it a livesampler thing using core that you are talking about? because my attempts have had problems but never that bad. ive found that for beat material, lniking the grain engine to the master midi clock works well. what i do, is take the song position clock at whatever beat division, and modulo that by 2 and use the mod output. this gives a 1-2 count (actually, a 0-1 count). in core (where my phase osc for both the lookup and core array samplers are), i have 2 merges, and 4 latches. when the grainclock = 0, a latch triggers a 0 for grain A, and a 1 for grain B. when the clock = 1, the other latches trigger a 0 for grain A, and a 1 for grain B. What this does is effectively give a pulse waveform, with a full period half the rate of the master clock rate. i then trigger the grain reads at each grain's 1. also, i take the pulse waves i made and smooth them (using a slew limiter in primary, and my own slew limiter/smoother in core). these then become the window functions and are multiplied by the sampler's outputs - in primary, i had to use 2 voices for the lookup sampler - for audiotables and core arrays this isnt neccesary since you can have multiple clients/OBC chains.

attached below is a core version of what im talking about. the only real issue is that when recording first starts, there is a stutter that occurs, im not 100% sure what is causing this, though.

I really didn't watch all your moovie. cracy stuff, and so are you, just insane. do you comment your going to the toilet the same way like you commented your pushiin the buttons on your moovie?
You are just insane, let someone help you, let someone save your soul, honestly, just insane (the negative way)

i checked that patch it's pretty much like the one i built. But i'm using lookup table for everything... and also using the lookup table pos to make things go in reverse, slow down, and hold. But here is an early version of my patch http://www.lostscience.org/reaktor/showyou.zip this is like verison 12 out of 80.. but you will get the idea of what it is doing .
thanks

Hmm, you are talking and showing here an actual version only per video and you want answers about a very superficially described harware-software problem. Then you send a very old version of your ensemble. Do you fear that anyone will copy your ideas?
It's like going to a doctor and saying: oh i am having antinode bulge pain can you help me? I can show you my fever curve and a video from last year i had cold.

actually the grain sampler is exactly the same one one in my newest patch and they both have the same problem. I feel like I have the right too not have to give away all my hard work for free to everyone on this forum. I mean I did spend more 6 months building this thing and a view it more of a composition then as a piece of software. I more of the mind set of sharing with people that share a like. I hope you understand this.

[Belial]

its a shame you feel that way, it looks like it could be a good learning experience for a lot of people. also, i vaguely remember that herw's modular mini 1 and 2 took more than 6 months, same as emeyers marx.
i can sort of understand the whole protecting your work, but still, its a shame...
and i assume you've used user library creations? other peoples hard work that they've given away for free.... :P

[kid_sputnik]

anywhos, im going to look at the patch, but im wondering, did you notice similar things going on in mine? meaning, did the pitchshifting sound the same?

usually the biggest problem i found is that there is horrible clicking if you dont window perfectly, never had horrible aliasing.

one more thing, the quality of the lookup sampler isnt on "poor", is it? because i believe that means interpolation is off. i usually find "good" quality to be more than fine.
