Recorder buffers for looping and live sampling

Spheric_El · 2019-02-20T07:08:56.546Z

Hey you guys are getting deep.
Don’t want to derail too much but a quick question…
Can I record quantized loop lengths longer than 64 (when not at 120 bpm)?

You can use Rec Setup 2 Qrec and start / stop recording quantized. This can’t be automated except with midi loopback and midi tracks.

You can also divide the tempo.

Good idea.
With Midi track configured in PER TRACK + TEMPO MULTIPLIER and a Trig in the first step to start recording and in last step to stop maybe. Or with a pattern change, A1 with the start Trig (one shoot) and a A2 with the Stop Trig, manual change pattern from A1 → A2, or arranged (X cycles), or making a change pattern via foot controler too (in the Midi chanel).

OTs quirky in that any recording over 64 steps you can start either manual or with a one shot recorder trig, but you must define the end of the recording manually, there’s no automatic record stop for recordings over 64 steps.

Turning dynamic recorders on in the mem config is the easiest way for the recorders to have ram for long recordings, when you turn this in you have to power cycle after because of a current bug. Recorder setups have trig modes, you use “one2” mode to be able to manually end a recording. “Qrec” is the quantize record setting so by setting that to 64 for example you can enter a start recording command (track+rec) and the recording will start at the begining of the next pattern cycle, press (track+rec) again during a pattern cycle and the recording will finish at the end of that cycle (assuming 64 step pattern). For some reason there’s a new bug in the latest OS where you have to press (track+rec) twice to stop a one shot trig recording, for manual or on OS 1.25 H you only need to press the combo once…

Hey thanks folks for this definitive answer

Open_Mike · 2019-03-29T00:49:34.955Z

Mann… I just went to automatic sampling for my guitar, next level for me… Instead of using pickups, manual sampling, or one shots, I’m setting tracks to 1/8 scale and setting solid record trigs to sample a thru track+neighbors with input my guitar. I’m using rlen 64 and having the OT just sample every 2 or 4 pattern cycles. I have multiple flexes playing the buffer using start point locks, reverse rate, other plocks on things… I just keep playing now and every once in awhile the buffer is updated so new stuff comes out all reversed, sliced, pitch shifted, warped to all get out underneath what I’m playing…

I’ve got scenes set to do things like raise lfo depths that target retrig and retrig time on the warped flexes, others to activate freeze delay on guitar and filter the master so I can get crazy breakdowns and play over it… On another recorder track I’m doing the same for rytm patterns and have a chain going on rytm so the buffer remix gets updated automatically with different material as well. On some recorder trigs I’m sampling both the guitar and AR into one buffer and throwing that on a remix flex…
Blast off!!

I’m setting tracks to 1/8 scale

Scale pattern only admit 1/16 min value, so do you refers to TEMPO MULTIPLIER 1/8x?
Seems a funny workarround!

Obviously yes, that’s the whole point of slowing down the tempo when you don’t need the default resolution for your trigs, becuase there’s only one that fires every once in a while on the 1st beat

Soham · 2019-03-29T11:08:46.723Z

Thanks for the clarification, I had not thought of that way of having recording triggers in pattern cycles 2, 4, …

Open_Mike · 2019-03-29T13:46:56.701Z

Haha… It’s funny because the whole forum requests “individual track scale” for the other boxes and I’ve corrected by calling it “tempo multiplier” a few times. Finally I just figured I’d call it track scale so folks knew what I was talking about. For Model:Samples they’re just calling it scale now probably because we all did anyway…

A track at 1/8 gets you the equivalent of 8 64 step pattern cycles, assuming your using 64 step patterns which I almost always am. I’m using a thru and some neighbors each with no play trigs so those are good places to have the recorder track as scale won’t affect any playback. I started with a record trig on step 1 and step 33 so it records a pattern cycle length sample (rlen64) the first of every 4 cycles, but you can of course change it up in all sorts of ways.

I recorded a video (my first ) the first day I tried it and YouTube wanted to take hours and hours and hours to upload with my current connection, maybe I’ll get it up from somewhere else or I might try to make a better one next week…

My ADSL connection has (at best) a 1Mb/sec upload speed so I use my cellphone that has 4G @ (at least ) 20Mb/sec upload speed configured as a Wifi hotspot. Might be worth considering if haven’t already done that

Thanks, I do use my IPad cell service to connect. I live in the mountains and recently moved a bit further from town to a place with dodgy reception. If I drive to town it will work a lot better…

Hi, please correct me if I’m wrong. What you say is true, because we consider length (I mean, time) here. We don’t get 8x64 steps. It’s the equivalent in terms of time we get, at the same BPM. But at the expense of resolution: per page (we are talking about virtual pages right now) we now only have 2 steps instead of 16. If we have a track that runs alongside with default resolution (in scale-per-track mode of course), and we take that (musically) as the reference track (like we would do naturally if this track is a drum track that defines the groove, trigs that we put on the 1st and 2nd trig-slot will be played on the 1st and 9th beat. If we need a trig in between, then we might use microtiming but there will still be 1 trig per trig-slot.

I thought that needed to be made clear to avoid confusion for other users that might read the thread. (As I was at first with these scaling options)

Open_Mike · 2019-03-29T19:53:04.865Z

Yeah that’s right, it lasts as long as a normal X1 track repeating 8 times. I think you also need to set the master pattern length at 512 so it doesn’t get cut short, mine was already set there when I tried this. Since at the moment I’m simply working with rlen64 recordings and launching them at the beginning of X1 equivalent cycles, I use steps 1, 9, 17, 25, 33, 41, 49, and 57…

My posts don’t always have all the uber specific nitty gritty details, but they have enough to show the concept and I figure folks will learn a thing or two along the way while figuring out how to achieve similarish results, maybe they consult the good helping book, aka the manual. There’s no way I’m going to explain everything on every post or I might as well make a new manual/guide book…

Folks can always ask me for clarity if something doesn’t make sense. I speak a bit more vaguely than a tech reference and often I’m not giving step by step instructions but just stating a concept, often nauts will know what I mean and if they don’t they can ask and I’ll clarify. I give step by step more when someone asks a question and I answer it.

But thanks for adding some details I’m sure it helps…

Happy Octatracking my peoples

Has anyone experimented using midi triggered recording using an external sequencer? I have never tried but I think that with a sequencer that offers decent note length resolution, precise length recordings could be made, probably would need to fiddle with settings to get optimal results for sample accurate length, but I think it could work. Thinking out loud.

Open_Mike · 2019-03-29T20:19:55.197Z

I haven’t really worked up to MIDI loopback yet, although I’ve contemplated it. That might be all it takes! I’m still on 1.25H, one of these days I’ll upgrade and at least get conditional sampling working with loopback… Long automated recordings also seem doable… Track tempo multiplier on regular record tracks with rlen:plen I think might work too…
(also thinking out loud… )

I have posted a way of doing this less than a week ago. There’s a .PDF in the file section. I use a midi footcontroller and midi loopback, but you can substitute the footcontroller with an external sequencer, it’s the same procedure. I wouldn’t count on sample accurate recordings though. Midi has latency.

Open_Mike · 2019-03-29T21:02:42.646Z

Right, Nice! I should have recalled that.
I’m running on sleep deficit lately… I quit smokin the good Cali and can only sleep for five or six hours as some sort of result…

Yes I read it, good stuff The reason I mentioned using an external midi sequencer though is because I need to use the midi ports, so as I don’t have a sophisticated midi router (I use an oldschool midi patchbay) midi loopback isn’t always* going to work for me. I think it might be possible to get sample accurate if the quantized recording settings and incoming midi are right - at least for the start of the recording, for the length I’d probably go for say 16th note longer then trim to exact bars in OT audio editor. So in this case the OT would still be governing the sampling length/timing, the midi latency should not be a factor.

*Depending on what I’m sampling.
