Hi all,
Another update to pd-bl:
https://gitorious.org/maximus/pd-bl
I added a 4x upsampled version to the example patch, together with a 10th-order lowpass filter to prevent aliasing when downsampling. The harmonic content is much more present in the top end, the non-upsampled examples now sound very muffled in comparison.
Note that it is crucial to put the phasor~ in the upsampled patch, otherwise the phasor~ will be aliased before even getting to the bl-tabread4c~ -- garbage in, garbage out...

Disadvantages:
- The higher harmonics are reduced compared to an optimal method.
It seems 4x upsampling fixes this, but CPU usage will be higher.
Enjoy,
