They’re both limited, but the limitations play out in different ways.
If the lack of attack parameter is a real sticking point for you, I’d go with the Samples.
I use the start point to shave off kick sample attacks a lot, making bass lines from them. Can’t do that with Cycles, but I can still make great bass lines with Cycles. They’re just different.
If the lack of a filter on most machines is a real sticking point for you, I’d go with the Samples. I use the filter to make just about any kick sample work. Sometimes the Cycles kicks are too clicky for my tastes, and I wish it had a filter. Really the filter is the star on the samples. I LFO it and trig-less lock it on just about everything. With the LFO envelope shape, it can do a lot of things. And the combined HPF/LPF on one sweep knob is wonderful. Automating the filter can completely transform a sample.
If you’re really into the sound of FM synthesis, and Macro control… I’d go with the Cycles. You’re just not going to be able to modulate anything other than pitch/decay/start/length/filter/dist/fx/pan on the Samples. But on the Cycles you get to modulate macros of the synth parameters, and that’s where the magic is. Things can get real far out and varied, spacey… good times.
If you’re willing to let the tool define the path (and perhaps the final destination), I’d go with the Cycles. I tried to make a noisy chordy techno track last night and it just would not happen with the chord machine. But I did make a groovy deep tech-house track, that I kinda like. It wasn’t my intention, but it was fun to go down an alley I don’t often venture through. As a friend of mine said, “sometimes it’s nice to try on silly hats at home that you wouldn’t wear in public”.
So that certainly gives it a “fun” aspect. And in this regard, it reminds me a lot of the OP-1, but without the frustration of getting sequences onto the tape.
So yea, pick your poison. But you’ll probably end up with both.
