I bought the PO-35 as an addition to my 8 vocoders and various other synth engines and samplers. This is a very useful device if you want to create artificial vocal effects quickly and with good audio quality. You can record your spoken phrases using the built in microphone or line input. This recording is used to drive the various synth engines the PO-35 has on offer. If you are looking for a sampler then this probably isn't the device for you, there are other things to buy for sampling. You need to keep in mind this is a voice synthesiser and not a sampler in the true sense. I've had some great results so far ranging from Kraftwerk styles, Daft Punk etc. Very quick to use but you will need to spend a little time learning the various keyboard shortcuts of which there are several. I'm putting together a cheat sheet to remind myself as I don't think I'll remember them all and there are some functions that aren't listed in the manual but you can find easily enough by searching on the internet for PO-35 secrets. I really like trying ideas and they sound great. It is a shame the silicone cases are so expensive, I just can't bring myself to pay for one. It should be fine without a case if you are careful with it. If you like voice synths then this is the device for you.
