Thanks for the link! I’ll take a look at the script.
In the svp files created by Synth V, the tempo information is actually saved with one decimal place. If you manually change the tempo values in this file, Synth V will also adopt them correctly!
{“version”: 153, “time”: {“meter”: [{“index”: 0, “numerator”: 4, “denominator”: 4}], “tempo”: [{“position”: 0, “bpm”: 60.5}]},
