Well, after spending so much time with my Matroshka and pretty much testing ANYTHING, I decided to send it back. I bought it on Amazon, I can easily get another one later if I want.
Don't get me wrong, it's an AWESOME synth pedal that works extremely good. I don't take back any good thing I've said about it, but I decided to follow a different path.
If you're not too much into synth stuff but you need a small pedal for a couple of songs, or even if you are a synth junkie and want to have a lot of sounds in a small package, this pedal is absolutely perfect. 2 is even better, in this case.
Personally, I've always preferred to get into synth territory combining different pedals instead of using just one. I've found that my favourite synth tones on the Matryoshka were just little variations of the same I was getting with my other pedals. Matryoshka does A LOT more stuff of course, from arpeggiators to lead synths to whatever you want. I wasn't using those sounds with my band, which does also electronic stuff.
I also must say that I hated turning all those knobs over and over, maybe presets would be an upgrade. I say this because each preset has at least 2-3 usable tones, you can do a lot of stuff.
The envelope function on the input of the pedal can't be turned off completely, even with the sensitivity dimed.
I prefer having a strong compressed/defined attack and I do sweeps/filter stuff with an LPF+expression pedal, so I don't need that specific function. I'dd add more range to the sensitivity knob or a switch to disable it.
If you like that function, the pedal is awesome. You can adjust the sensitivity and do beautiful synth sweeps just using your dynamics.
