This version is backward-compatible down to version 1.4.
Preset/bank files as well as sessions created with version 1.4 and later will be accepted.


Due to technical limitations the PSP 84 version 1.6.0 is available in the non ilok version only.

Plug-in will ask you to put the valid authorization name and key on startup they should be listed on your account at our registering center.

Lexicon PSP 42 Version History

**** 1.6.0 ****

1. AudioUnit supports MAC 64bit (x86_64) natively.
2. GUI is Cocoa-based (no more Carbon). Audio application capable of hosting AudioUnits with Cocoa view is needed to run AU. Minimum system requirement for AU is OSX 10.5.
3. Plug-in has been built with new version of graphic library and benefits from event-driven architecture.
4. New version of presetbar is used. It allows for setting default bank and preset by double-clicking on 'bank' or 'preset' at the bottom bar.
5. Plug-in uses chunks to save its state in session file. Entire bank is restored on load.

**** 1.5.3 ****

1. AudioUnit PowerPC <> IntelMac session portability issues resolved
2. GUI responds fine in Digital Performer
3. Faster gui refresh rate
4. Default bank feature implemented (apple/ctrl click to restore factory bank)
5. PC/PPC/IntelMac bank/preset file portability issues resolved - CHECK

**** 1.5.2 ****

1. Plug-in works fine as AudioSuite
2. Samplitude crash has been fixed.
3. Feedback signal is not 'retriggered' when changing delay time.

1. DirectX format is no longer supported.

**** 1.5.0 ****

1. Build with VSTSDK 2.4.
2. 64-bit VST host<>plug-in stream supported.

**** 1.4.1 ****

1. AudioUnit - plug-in parameters can be controlled by MIDI CC messages.
2. AudioUnit - MOTU DigitalPerformer 4.5.2 crashed when plug-in was launched. Fixed.
3. AudioUnit - the automation did not work in MOTU Digital Performer 4.5.1 and later. Fixed.
4. AudioUnit - the plug-in does not cut audio when the soundbite ends in MOTU Digital Performer.
5. AudioUnit - mono->stereo configuration works fine in MOTU Digital Performer.
6. RTAS - loud click was audible on plug-in instantiation somtimes followed by a crash. Fixed.

**** 1.4.0 ****

1. Totally new, platform- and host-independent preset management system.
2. MIDI learn function with cross-platform MIDI setting save/load option.
3. Further optimiziation.

1. Parameter edge filtration caused denormalized number problems resulting in high CPU load for certain settings. Fixed.
2. Sudden and random jumps of the feedback knob to 0 position no longer occur.
3. Cross-compatibility issues with Native Instruments products have been fixed. No more reauthorization problems.

**** 1.3.0 ****

1. The phrase sampler has been completely rebuilt to exactly reproduce the properties of the original Lexicon PCM42:
- when in DLY mode and RPT oo button is hit, the plug-in immediately starts looping of the audio that's already in the buffer,
- when in CLK mode and RPT oo button is hit, the plug-in starts to loop as soon as the beginning of the next bar is reached (provided the host application is capable of sending song position information to the plug-in),
- both input signal and feedback are captured,
- it is now possible to mix input signal with the loop while in RPT mode,
- it is now possible to punch in the the new audio by switching the RPT oo button off and back on. If the feedback level is high, new material is mixed in with the existing audio. If the feedback level is low, the new material replaces the existing audio.
- once looping mode has been deactivated, the contents of the loop is fed back (echoes are generated) provided feedback is non zero.
2. The phrase sampler on-the-fly crossfade is exponential (was linear).

1. When delay time was near zero, the antialias filter was not working. Fixed.
2. The crossfade time (applied when delay time is being changed) was host buffer size dependant. Short buffer settings resulted in audible clicks. Fixed.
3. DLY<>CLK switch is now disabled while in RPT oo mode.

**** 1.2.0 ****

1. Headroom meter falloff time depended on the host buffer settings. Fixed.
2. MIDI control for discreet parameters has been corrected.
3. The cause of occasional crashes when GUI window was being closed has been fixed.

**** 1.1.0 ****

1. Pentium IV optimization - now requires about half the previous CPU processing power.
2. Tempo delay numerator and denominator are now MIDI-automatable.
3. Improved Logic Control support for numerator and denominator parameters.
4. First preset now contains the default values for all controls. This allows Logic Control users to restore defaults correctly.

1. Loud feedback that emerged after several minutes of plug-in activity has been removed.
2. Interpolation algorythm has been improved - previous version was inaccurate with high modulation (depth) settings.
3. MIDI automation for discreet parameters has been corrected.
