After working a lot with tempo-changes over the last years, I've reached some conclusions:
- In music, tempo-changes are always curves (never straight lines)
Unfortunately it seems to me that DAW's (Digital Audio Workstation) use mostly step-based tempo-changes (This is similar to digital interpretation of audio-waveforms). I can understand this from a technical point of view, because the tempo is the foundation for a song in the DAW, and then needs to be rock steady.
However I would like to see a DAW with:
- Tempo-envelopes (at least Reaper has this today, but only flat lines)
- Nodes and curves
- Vector-based, or mimicing vector-based curves
- Record tempo-possibility (Example: You can use an expression-pedal or midi-slider to adjust and record the tempo as you play along)
..but, I'm a dreamer :)
