The Take-5 is by far my favorite synth. It is hands down the best synth I have ever played or heard. It could be so much more powerful if it had a 3rd envelope for modulation (preferably looping), one shot lfos, a more subtle/musical overdrive that doesnt get blown out as soon as it's audible, and slightly better fm which is decoupled from the osc2 volume knob for more control over waveshaping. There's nothing to replace it with, it is the best synth around. So I can only hope that there is a firmware update that addresses at least a couple of these issues.
I would definitely pay $2000 or so for a Take-5 with 8 voices, a second svf filter, a 3rd osc, 3rd looping envelope, desktop (keyless) module with maybe a couple more lfos and the graphic visualizations that the pro3 uses, for preset design.
Slightly more usable fm would be ideal, but i do love it already. I just think it could potentially be better if we had more flexible control over it. fm is by far the most exciting aspect of this synth, pairing it with osc sync is the coolest thing ive ever experienced on an analog poly, especially one that sounds this incredible. I just think it's not very far off from the absolute perfect dream synth. it wouldn't take much.
maybe once more people start giving it the attention it deserves, we can get either a new desktop version with a few more features and improved synthesis options, or at least a nice little firmware update. I am crossing my fingers for either to become a reality sometime in the near future
