Player/Recorder ModeMultitrack EditingSettings > All Settings > Project > Mixer > DSP Saving : Special modes section.This mode allows big configurations (such as 48 x 48 channels) to run on a single board. Player/Recorder Mode isintended for use with an external hardware console. When this mode is activated, the Pyramix mixer is relegatedto the role of signal router, there is no level control, no panning, no plug-ins and no inserts. This option is onlyavailable in configurations with multiple mono mix buses.The Pyramix Direct Out functionality provides an alternative, more user configurable, method of achieving similarDSP savings. Please see: Channel Direct Outputs on page 164Pyramix is ideally suited for editing multitrack recordings. Grouping clips across all tracks used for the recordingallows edit decisions to be made while listening to a single track or several with the resulting edit changesreflected in all the clips in the group. Track Grouping functions enable you to work in a way that suits you. TheSource - Destination editing model is just one possibility.Please see the following sections:Grouping Clips on page 113Track Groups on page 81Source - Destination Editing on page 132Editing with Limited HardwareMulti-track recordings with many tracks (E.g. 48 track 96kHz 24 bit music recordings) can be edited on hardwarewhich cannot support this number of tracks. (E.g. a laptop) Simply mute tracks that do not need to be heard usingthe button in the Track Header. Tracks muted here, rather than in the mixer, no longer access the disk. Providingthe Multitrack recording’s Clips are grouped across all tracks, then any editing changes made on the tracksused for the editing guide sound will also be reflected in the muted tracks.LTC syncEXAMPLE - where a cinema projector must be the master• Cinema projector follows mains (or is crystal controlled) and sends biphase signal to a Biphase -toLTC converter. (E.g. the Rosendahl BIF)• Converter’s LTC output is directly fed to Pyramix LTC input• Pyramix is set to "LTC sync" mode and will adapt it's own internal clock to sync to LTC whenever thePyramix is set to lock and the external LTC is recognized to be playing at about 1x forward speed.• Pyramix feeds it's own clock to the DA-88 (or similar machine used as an A/D converter) via Wordclock.• The DA-88 (or equivalent) is set to sync to external Wordclock• The DA-88 in turn provides the Pyramix TDIF daughtercard input with digital audio data.All LTC sync ballistics in the Pyramix software have been carefully designed to both allow a large locking range (-7to +5%) while still exhibiting extremely low instantaneous jitter and more importantly a controlled maximumspeed change slope - not more than about 25 PPM per ms (25 Parts Per Million/millisecond) - in order to make surethat any other digital audio equipment connected to it's Wordclock output is provided with a smoothly changingclock speed (free of any abrupt speed changes). When used with Tascam digital multi-tracks such as the DA-88 thisin turn allows the TDIF input decoding circuitry in Pyramix to properly decode the digital audio data at all timeswithout disruptions while the complete system follows the actual master speed changes.Driving the pyramix with the LTC output of the DA-88 is maybe possible in some situations but will demonstrateseveral limitations which should not occur if you precisely follow the recommended setup as described above.Applications : LTC sync 19 - 340
