v2.3 (2021/04/20): bug fixes and MIDI release

SynprezFM suffers from 2 major problems: sound not loud enough, and incomplete MIDI support. These are not really bugs, the former being due to the fear of digital saturation and the latter the impossibility to test all the MIDI controllers on

the market. Nonetheless, a user discovered a real bug, a discrepancy of pitch between performance and recording, so I decided this was the time 1/ to add a limiter on the global output 2/ use the MIDI Android libraries for a better MIDI support (including wireless keyboards) 3/ fix a couple of other bug):

• limiter to enable louder sound

• MIDI support based on Android libraries to address more MIDI controllers

• storage access rewritten to solve first time access problems (and support Android 11+)

• pitch discrepancy on recording (48K vs 44.1K) fixed

• wireless Bluetooth MIDI support

• "MIDI slave" support

• support for multiple MIDI keyboards

• finer volume and balance scale, wired on MIDI

• "Scoped Media" storage mode, mandatory for Android 11

• peak indicator on VU-meters

• drop down menus with pseudo LCD

• output volume operating after the FX processor

• description of the device capabilities in the configuration page

• better MIDI traces to diagnose problem

v2.2.4 (2019/04/28): Android Pie bug

This release was unplanned, and not in the roadmap. It was due to a bug that appeared in Android Pie, related to a difference of size between screen and top window in full screen mode. Anyway this is fixed now so the other evolutions are:

• new stack mode to control two synths with just one keyboard

• consequence: it is possible to control the transposition, balance and delay for each synth separately

• popup to control which strips are displayed and which are not, instead of menu and submenu stuff

• removal of a couple of languages I was in trouble finding support with

v2.2.2 (2014/11/30): minor

• ergonomics: better color for active surface, and arrow to show sliding widgets

• USB detection

• MIDI pedal polarity inversion

• MIDI logging support

• bug in silence terminated sequences (no loop!)

• bug in saving patches

• better ergonomic when saving patches

• skeleton keyboard when loop mode is on (keys are disabled)

• right justified digit

• "dot" when patch is edited

• propose to save an edited patch before changing patch

• lot of new languages

v2.2.1 (2014/11/03): major release

• low latency drivers for Android 2.3 and above

• export in WAV

• experimental: support for MIDI USB for Android 3.1 and above

• sound classification (tags)

• user defined loops to feed the arpeggio

• new display mode to use 2 synths on small but powerful devices

• better ergonomics

• micro-tuning and temperaments

• new effects: phaser, pan and reverb (actually, between echo and reverb)

• Italian, Portuguese and German languages

This release may be not perfect, but the roll out of Lollipop (Android 5.0) made it mandatory on Nov 3rd, because the old version in the store would not work on the new ART virtual machine (replacement of Dalvik)

v2.1.1 (2013/03/27)

bug fixing (default volume, lazy sliders, stereo chorus etc.)

• arpeggiator

• keyboard dynamic settings

• better contrast on texts

• russian language

v2.0.1 (2013/02/05)

• patch editor

• 1024 builtin patches

• LED and LCD à la DX7

• 100% custom widgets

• better ergonomics

• more controls on the main page (volume, portamento etc.) + vu-meter

• fix of feedback on algorithms 4, 6 and 31

• key width adjustment

• reverse keyboard à la harpsichord

• new effects: taps, echo and chorus

• explicit setup of external storage directory

v1.1.0 (2012/08/09)

• performance menu

• portamento

• after touch

• pitch bend and modulation wheel (large screens only)

• second keyboard (large screen only)

• light stereo delay (I know, this is not a DX7 feature, but it makes the sound less dry)

• online help on each menu

• automatic volume adjustment (not a good idea actually, removed in the next version. Using the combination of user's brain and ears is much more efficient!)

• support for Intel based devices
