I love Renoise. However, a couple things need to change until it becomes my flagship sequencer.
I need to be able to dump patches from my hardware into Renoise. It would be great if there was a buffer for every track (a track assigned to ext machines) that would allow me to store a patch (i.e. from my Virus) and then load it to the ext machine when the song loads. This has hindered me from using Renoise in a live situation.
Another problem, again making it difficult for rock solid live performance, is the fact that I cannot consolidate my samples with the song very easily. I would like to be able to quickly consolidate my song into a folder containing all used samples. That way, if my computer fails I can easily load it onto another without dealing with the relinking of files.
A pattern sequencer would be nice but it does not exceed priority over the matters stated above.
If a pattern sequencer is to be implemented in renoise PLEASE allow me to assign midi cc and midi notes to individual steps on the pattern sequencer so I can use my midi keyboard for instance to emulate the running steps on say a tr-909. I still to this day have not found a decent software step sequencer that lets me do this. I want to be able to punch in steps on the fly with my midi keyboard and then assign a control to switch through layers like the old days.
