The keyboard tracking now also scales + cutoff frequency, not just resonance. + - fixed bug in sysex handling (patch by Juan Linietsky) + + * LSCP server: + - fixed application exit on broken pipe error (fixes bug #20) + + * MIDI driver: + - fixed legacy sysex code which caused dispatching of MIDI SysEx + messages several times instead of once + + * general changes: + - support for muting sampler channels and solo mode of the same, two new + LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new + fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were + introduced for this, the behavior is the same like on a mixer console + (patch by Grigor Iliev, a bit adjusted). Also added configure option + --enable-process-muted-channels which can be used to enable the + processing of muted channels. + - support for sostenuto pedal + - support for monitoring the total number of active voices; + (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX, + SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT) + +Version 0.3.3 (15 July 2005) + + * packaging changes: + - fixed compilation with gcc 4.0 + + * Gigasampler format engine: + - LFO preprocessing was performed even though the respective LFO was + disabled by the instrument patch (minor efficiency fix) + - if period time of chosen audio device is too small (< MIN_RELEASE_TIME) + for volume ramp downs in the same fragment (needed for current voice + stealing implementation) then simply inform the user with a warning + about possible click sounds and reduce the volume ramp down + appropriately instead of cancelling the audio device connection + +Version 0.3.2 (24 June 2005) + + * packaging changes: - updated autotools build files to compile on OS X (conditional compilation of CoreMIDI and MidiShare drivers) - hand-crafted assembly optimization code can be disabled with
