- 🆕RDX - FM Manager - AUv3: its developer released another app: Tonic Piano
- 🆕RDX - FM Manager - AUv3 first spotted by AppInsider#45 in Top Paid · All Apps · Brazil
- 📦RDX - FM Manager - AUv3 version 1.9.0• PITCH ENVELOPE (PITCH EG) — the fourth envelope of the classic cartridges finally plays: the clang on a bell's attack, the rasp of brass, the "bloop" of a bass. Nearly a third of the voices in a typical library ask for it, and until now it was read from the file and ignored.
• FEEDBACK ON ALGORITHMS 4 AND 6 — on those two the feedback control did absolutely nothing, and the loop always ran at the operator's full level. Now it follows the voice: one asking for zero feedback sounds clean, like the original instrument.
• FIXED-FREQUENCY OPERATOR BACK IN TUNE — the law is logarithmic, not linear. Bells, percussion and effects using a fixed-frequency operator were up to an octave off.
• OUT-OF-RANGE TRANSPOSE — a library file with garbage in that field played dozens of semitones high, a shriek. It is now clamped to the format's range.
Same in the app and in the AUv3 plug-in — the plug-in was re-registered, so your music host picks up the new build.… more - 🆕RDX - FM Manager - AUv3: its developer released another app: Tonic EP — Piano Elétrico
