Much finer groove control

[colb]

I think it's important to maintain the open flexible functionality of the groove column.

e.g. For creating long slow phasing sequences, the current groove settings don't work, 

you already can do almost all Raich's "phase" pieces on Nerdseq easy. I think for phasing you should use "short" and simple sequences what become complex because of phasing. then it is easy to catch that simple melody and how it changes.

Yes you can use phasing techniques, but only using workarounds like running the internal clock at a very high rate, or using an external clock.
Running the internal clock at a high rate works, but only at close to maximum bpm, and at that rate syncing tracks starts to get tricky because the ruler indicator is flashing across the screen so fast - it's a proper workaround for sure
Using an external clock works, but for me, a big part of what something like Nerdseq is about is that it can be the foundation of a track, it shouldn't require to be controlled externally unless that's required for other reasons (DAW synchronization etc.)... and the ruler still runs too fast.

I think you are kind of missing the point of this request though - it's not just about phasing techniques, that is a single example to support it. It's about the fact that the two fundamental elements of music are pitch and timing - and it's arguable that timing is the more important of the two. Nerdseq has limitations in terms of the control it offers over timing. That's what this request is about - giving us composers more flexibility and control over one of the most fundamental components of music.
If it's not possible due to technical limitations, then we have to accept that, but if it is possible, then IMO it should be a high priority.
