Greetings.
I know this is an old conversation, but I want to say my idea anyway, because I use the looper a lot.
Many argue that the maximum loop time is not an important issue. For me it is not true.
I use the looper essentially to play solos on structures that I recorded while the singer sings the song.
For example, in the first chorus the singer sings the song, I play the chords and record the loop. In the second chorus I loop the recording and do a solo. It is typical in jazz oriented.
The average structure of a song has 32 bars. If I imagine the 60bpm time of a ballad, we will have 4 seconds per beat, which in 32 is 128 seconds, more than the maximum allowed.
This means that I cannot use it to improvise on every song, and on many I will be dangerously at risk of sudden stop (this in mono and at half speed ...).
As far as I'm concerned, the increase of a few seconds would be enough to make it usable.
Instead at the moment I am forced to wire another additional pedal, which is what I would NOT want to do, having a machine like Helix available.
