Revision History - v7.00
Daqarta v7.00 - 18 July 2012
Enhanced macro system now supports math expressions and operators (including built-in e and pi constants), math functions (including logarithmic, exponential, trig, and hyperbolic functions), 80-bit floating-point variables, arrays (including FFT/IFFT spectrum functions, special math, display, and file operations), multitasking, custom controls dialogs, and custom resizeable meters.
Control macro commands can now be used in expressions, such as L.0.ToneFreq=sqrt(R.0.ToneFreq * R.1.ToneFreq).
WHILE / WEND loops now supported.
Macro Comments now support extended multi-line format to allow easy disable/enable of command blocks during development.
Pre-installed macro examples and mini-apps (with Help tutorials) include Monaural and Binaural Beats, Channel Difference (A-B), Engine Crank and Cam Sensor Simulator, FFT Filter, THD Meter, IMD Meter, Phase Meter, Lissajous figures (X vs. Y), Chart Recorder, file conversion, thermocouple equations, and new Phantom Signals auditory phenomenon (possibly relevant to "dental radio" and Electronic Voice Phenomenon).
New Properties dialog in Help menu allows verification of Daqarta's Digital Signature. (A missing or corrupt signature may indicate a virus or malware infection. Always download the latest version of Daqarta only from www.daqarta.com.)
Daqarta now accepts the emerging industry-standard Frequency Response Data (.FRD) files supplied with some calibrated microphones. This file type can be used as-is for relative calibration via Spectrum Curve, or you can add Unit and Sens lines manually and load it instead of a .CAL file as a microphone calibration file in the User Line dialog of the User Units option. This will behave exactly like a .CAL file to allow absolute SPL readings on the Y axis or via the Sound Level Meter option.
Spectrum Curve file open now allows selection of microphone or other calibration (.CAL or .FRD) files, even on uncalibrated systems. If applied to Input channels, the .CAL curve is inverted to correct the input to apparent flat response.
.CAL, .CRV, and .FRD files now accept up to 4096 lines of data.
Added new Minimize Daqarta Window (Minimize) macro.
Reduced CPU usage during idle loop.
MIDI expressions now allow MIDI commands to be used as variables, where they return their current values. For example, I2=I1+1 will set the Instrument number for Voice 2 to one more than that for Voice 1.
When a MIDI instrument number is changed dynamically via a Iv=n script command, the new number and name are shown "live" on the Pitch-to-MIDI dialog and/or the corresponding Voice Setup dialog as though selected manually. Likewise for Instrument On/Off state and Tempo.
MIDI Changes script can now read current mouse position to allow mouse control over performance.
Bug Fix: Generator output Swap control could sometimes report wrong state.
