Version 2.3

Version 2.3 of Polyphone brings a better sample management and a more accurate sound engine, fully compliant with the sf2 specifications.

Samples

Stereo sample management

The stereo editing is now enabled by default and a button has been added at the bottom right corner. When the option is activated, any change occurring on one side of a stereo sample will be applied automatically to the other side, at the sample or instrument level.

When activated, the auto-loop tool creates the same loop for both sides of a stereo sample and the tool "remove blank at start" removes the same length from both sides of a stereo sample.

Wrong parameter detection

An algorithm automatically detects the quality of loops and possibly displays a warning at the sample level. Two levels of warning are defined:

red when the loop is obviously wrong (the loop points will introduce a sound crackle during playback)
yellow if the loop may be OK, or not (you need to pay attention)

bad loop detection - sample level

The sample summary also emphasizes wrong loops, assigning the same color yellow or red when bad loops are detected.

In addition to this, the sample summary points out configuration discrepancies for stereo samples:

tune correction mismatch,
root key mismatch,
invalid links.

When sorting rows, red or yellow elements will be on top.

Split

After having cut a sample using "Alt + click", it is possible to create another sample with the removed part. This feature can be handy if the sounds of the different pitches of an instrument are recorded in a single file: splitting the file is now straightforward.

Miscellaneous

OGG files can be imported
harmonics have been added to the calibration sine for low pitches, making the tuning easier
new tool scanning the instruments for filling parameters at the sample level

Sound engine

Tuning

Options in section "keyboard" have been added to change the tuning fork from 390 to 470 Hz and the temperament when playing - default being 440 Hz and equal temperament.

Compliance with the sf2 specifications

the release time was taken into account instead of the modulation decay
linked modulators are now working properly
LFOs use now a triangle signal instead of a sine
modulators using linear rules are more accurate

Improvements

the resampling now uses a 7-order interpolation instead of a linear interpolation, resulting in a cleaner sound with less artifacts
the reverb is disconnected if not used, saving CPU
