The original PO-16 (factory) operated at 48K samples per second (16 bit, mono), but that may not hold true for all, specially for the PO-32 that requires a lot of processing and the PO-33 that may have lmited flash for sample storage. It may not mather much for the PO-35 because the sampled signal goes through an algorithm and is changed into a very low rate “code” stream (maybe 50 per second) that are later synthesized back into sound.
Has anyone with the speak or ko noticed a high whining noise when using the line in or chaining the po’s together?
Is it possible to change the scale on the KO? I couldn’t see anything in the manual. Also what is the scale?
Haven’t had much time to play with it but some of the preset patterns sound great.
Is there any way to change the filter settings on a note after it has been entered? The only way I could find to do it was to change the filter settings and then re-enter the note.
This is becoming a rich thread.

Does scale apply here? Because a sample can be any note or non harmonic. Would the ‘scale’ just be straight steps up and down
Got both, in reply to my earlier comment it seems that speak can be used for non speech samples and its pretty good, so far vastly prefer speak to ko, ko is still good but speak has so much mojo. It is almost like a slimmed down version of roland v-synth’s vc2, but even better in some ways.
Saw elswhere that a pencil case/box could work as storage for mutiple POs as well as their batteries. Looking into this…
PO_35 : no way to mute or solo the drums channel.True there’s no dedicated mute/solo feature but since the PO-35 drum channel is monophonic by pressing and holding a drum sound 1-16 a drum sound will trigger but then the drum seq will remain “muted” until you release the button. To solo the drum seq press and hold any of the 1-15 “Speak” channels.

@szb9, This video shows a nice nonspeech sample.

It depends what you’re after… I actually rly dig the creative possibilities of non speech speak 
but you’re right that the speak will not yield standard sampling results if that’s what you’re after.

That’s rad… I wanna hear more.
Listening to a few examples would probably be the best, but I think that video above is the only one.
Generaly speaking, the LPC algorithm used in the PO-35 will take small overlaping sample windows of the input signal (20-30ms) and determine if it contains mostly noise (like in ‘s’ or ‘th’ sounds). If not, it will try to detect the frequency peaks (formants), but that is done without much accuracy. The results of this analysis are stored and used later for playback. The output is either a noise source or a pulse generator + multiband filter. The choice between these two and the filter parameters are adjusted continuously at the same rate of the sample windows. All the effects come from messing up with the original rate and/or filter parameters.

Well, you couldn’t convince me 
OK it sounds interesting but really sounds different than the original sound.

As far as I understood the PO-35 sound did not want to sound like the original one. 
Well, it is like asking someone to imitate a guitar (or any other non-speech sound) with his/her own voice. In fact it is worse because the PO-35 has very simplified vocal tract model. But the results may still be interesting.
I’ve had both for a couple days, and they are light years difference from each other. All the comparison/versus discussion seems ridiculous after using them.
Could any PO Speak user do me a favor and “sample” a kick or drum hit? I’m really curious of how it would sound…
Sampled a C. It seems key 5 plays the note you recorded unaltered. The notes surrounding it make up a combination of the natural minor/harmonic minor scale. C,D,Eb, F,G,Ab,Bb,B,C. I haven’t found a way to change scales, but you could record your own scale into a drum bank as a way around that. If anyone finds a ways to change the default scale that’d be super helpful!
