Teenage Engineering EP-133 K.O. II

With it having 64 MB of storage and a sampling frequency of 46 kHz at 16-bit depth, you can hold approximately 12.16 minutes of samples. This calculation assumes that the audio is mono. If you’re sampling stereo sound, the capacity would effectively halve.

Here is the math if anybody wants to check it:

Sampling Frequency: 46,000 Hz (which means 46,000 samples are recorded every second)

Bit Depth: 16 bits per sample. Since 1 byte is 8 bits, this means each sample uses 16 / 8 = 2 bytes.

Storage Capacity: 64 MB. To convert this to bytes, we use 64 MB × 1024 × 1024 = 67,108,864 bytes (because 1 MB = 1024 × 1024 bytes).

So, the calculation:

Size Per Second of Audio:
46000 samples/second * 2 bytes/sample = 92000 bytes/second

Total Seconds of Audio:
67108864 bytes / 92000 bytes/second = 729.44 seconds

Total Minutes of Audio:
729.44 seconds / 60 = 12.16 minutes (mono)

Technically, 64 MB is 64,000,000 bytes (nowadays) - 64 MiB is 67,108,864 bytes. :nerd_face:

Y’all are nerds and I hope you never change

If we did, most (all?) synth manufacturers would go out of business.

yes you can set it to only do a count in

Great catch on the MB vs MiB distinction. Using the modern definition of 64 MB as 64,000,000 bytes, the storage would be around 11.59 minutes, slightly less than the 12.16 minutes calculated using the binary definition.

Is there a reason one couldn’t simply put the output in the input to resample?

I might be way off base here, but won’t that create a feedback loop? Hopefully someone can confirm or dispel this though, because in this instance I’m not positive that’s correct.

Yes it would create a feedback loop because the sound would go out of the device back into it and out of it again and so on…
So resampling through the output and input could only work if the device could mute the input sound while still recording it.

It will work if there is a way to switch off input monitoring only.

But if you have a portable recorder (Zoom field, minidisc, …) you can use that. Not a big deal. Or get a used PO33 or some other tiny cheap recording item

Well, I caved and ordered one from B&H (they’re still in stock there in the US as of this post). It should arrive next Tuesday. Excited for the punch/-in effects, hoping it’ll be as fun as the Cuckoo vid made it look.

So it does loop then. :grinning:

Mine has been shipped from the TE store!

Absolutely. I had a Blackbox and sold it (I have the BitBox Micro, though) because of the sequencer. I had some hope they would implement a PO style sequencer eventually – I even suggested it in the forums – but after one of the latest firmwares featured a very strange revamped sequencer, I gave up and let it go.

I really hope they add a new PO-style sequencer mode to the 133, but doubt it.

“It’d be a bit more convoluted with multiple pages of course” – well, as it is now, the 133 has multiple pages, one for each step, so it would actually make it tighter than the current one.

I’m happy about copy and paste although selecting multiple bars would be ace.

Can one type in sequence position or how do you get around a long pattern? Can you start a pattern from the step you’re on?

With one of these for example. They cost like 1€

Although not sure if it will fit as the back seems pretty tight and thin in terms of height

it sold out quickly!

are the samples manageable separately?
can I create new projects?

ordered minutes after going live from TE. Got a shipping notice hours later. Still at the label created stage. Maybe itll actually ship tomorrow. Maybe monday. Hopefully i get it next week. Obviously dont fully understand the workflow yet, but it seems likely/hopeful well get some kind of bounce down of an individual group. If i was to say filter a bass drum I more often wouldnt want all of the drum parts in that group to have that filter applied. If i could save just that bass drum on one pad with the filter applied seems useful. Maybe its just a fundamental misunderstanding of how groups work and I could Plock these problems away. 33 had only 4 voices but each of the 16 samples could be filtered and pitched individually. 4 group/voice on 133 but then polyphony has me somewhat confused. Resampling would be killer though! The first update on the firmware page already has some thoughtful additions to it and this selling well and TE’s great track record on updates has me HYPE! the fader is giving me emu / isla vibes.
