Like most Teenage Engineering products, it's an absolutely amazing-looking, well-engineered product with a ton of functionality that does a thing I don't actually need for far more money than I can justify spending on it.
TE products tend to be poorly manufactured. Go look at an op-z that bends and causes double trigs, with soft non standard feet you need to turn to open to get access to the interior of the device. Take a look at all the pocket operators they break regularly (I owned 4 and two broke from even casual use) and you cannt get spare parts like screens from te.
And ton of functionality? Go take a look at the ob-4 a Bluetooth speaker with a radio, a sort of tape delay thing, and no audio out.
I used to be a fan of teenage engineering but the low quality of the products I've had of theirs and the extremely high prices have led me to a totally different conclusion.
This mixer is overpriced and requires super special teenage engineering slimline cables to fit all of its inputs at the same time.
I am looking for a portable mixer but this monstrosity by a company that has a history of quality issues is not the mixer I am looking for.
A sequencer for the /mixer/ is terribly terribly useful. Basically like having control parameters in a tracker, but for any arbitrary input you've plugged into the mixer. And knowing TE, I would be shocked if you couldn't target the mixer params with the sequencer. (Arguably, this is part of the value prop (hahahahahaha) for modular synthesizers.)
The synthesizer is probably more 'because they can,' once the rest of the software/hardware interface is in place. It's close enough to what they've already done lots of with the pocket operators; might as well throw one in so people can prototype sounds easily.
Lucky for you. Once I tried to copy a single audio file to my ipod without going through the whole itunes journey. Spoiler alert: In the end I just stopped using apple stuff.
It worked before the firmware update through a Winamp plug in. But to your point I will be avoiding this product in the same way I avoid Apple products.
