Sorry, I don't understand - are you saying to expect the sequences all to be in the key of C and some are in other keys?
Why are 1/3 of the sequences transposed on the AS-1?
I just bought an AS-1. I love it, but am having a difficult time understanding why you would transpose about 1/3 of all of the default sequences to a different note? This makes the sequences that are transposed unusable in a synchronized situation with another keyboard - where if you hit, let's say C on the AS-1 keyboard, you would expect for the base notes of the sequence to play in C - right? Is this a defect or a design flaw?
Every three or so sequences (Factory and User) is transposed to a key other than C. With these sequences, if I hit let's say E on the AS-1 keyboard it doesn't play in E. It plays in what ever base note the sequence was recorded in. This makes it very difficult to play along with on another keyboard that is not transposed to the same key as the sequence. There is also no easy way to change the transposed sequence to C.
my understanding of this is that a lot of the preset sequences were made by playing a midi file event into the sequencer. there are 500(!) sequences, and it seems there are some that were just longer than the 64 steps, there are a couple of sequences in triplets that lack a proper conclusion for them to loop correctly, that gave me the impression that a couple of preset sequences were done in a rush (so midi dump to the sequencer) without a thorough check up.
so it's a reasonable assumption that not all of them are in C. still, there are 500 of them, so it's not a thing i loose sweat over. if you find a sequence that doesn't suit you, it's really easy to overwrite them with your own. and then You get to choose the key.
