Description : VProm is a genuine Linn LM-1 VST that emulates all the symbols and internal circuits of the legendary drum machine based on the first sample in history. The Linn LM-1 drum module, invented by Roger Linn in the early 1980s
Linn LM-1 was a Drum machine in the early 80’s. It was used to form the sound of key artists such as: Prince, Phil Collins, Thompson Gemini, Stevie Wonder, Gary Numan, Depeche Mode, Michael Jackson, etc. So far, the unique sound of this machine is highly valued and only using samples the LM-1 output can not reproduce the wide range of sounds that this unit can produce, especially the tuning function and frequency content. The AM6070 DACs and the whole circuit stand next to the symbol patterns in this unique sound command.
for better installation, you must disable the Internet.
New in version
This plugin was previously called VLINN (before version 2.0).
The AudioUnit format still reports the placement of the old name,
and this means that you will find AU under the name VLINN.

In addition to the new features of the cross-platform version of VPROM version 2, there are some improvements and changes compared to version 1
New MIDI panel with MIDI-trained customizable trigger cards
Change the default MIDI Trigger Card (see the manual)
New panning capabilities for each drum, panning knobs will replace the regulator line with a pop-up window (available by clicking on the TUNE label in the graphical interface). See Control Panels)
Improved graphical user interface
Now all EPROMS can be replaced instead of 7 of them in version 1
Simplify and accelerate the download and management of custom EPROMs; You no longer need to specify the size, VPROM does it for you. After downloading, the user EPROMs are saved with a patch
The additional CUSTOM voice is renamed to EXTRA and is now loaded by default with the modified Snare stock (unchanged) (see Manual -> Downloading EPROM)
Double-clicking on the control resets to the default for most GUI controls
ALT + Left-click on each Tune control to accurately set the clock frequency by entering a value. The main information display will only show the last modified information or parameter value, for example, where EPROM .bin is loaded or pen, slider, etc. The current value
In addition to the initial speed mode, there are now 2 full speed modes with linear and now exponential response
The incoming MIDI message Pitch-Bend is now recognized and acts as a global adjustment offset, great for live modification of the entire set or for transferring up or down
VPROM now transmits its triggers as MIDI OUT
An external MIDI control interface can now only connect to MIDI CC messages (no more than Sysx or aftertouch)
The AM6070 simulated real-time decoding of the DAC: after an accurate decoding table for the data table for 8-bit companded incoming data. The real LM-1 nasty grid sound on every field, like the real thing, forgets to resample or customize the sample packets that will always seem boring at lower steps.
Hihat DATA looping and VCA: Hihat’s LH-1 scheme was pretty unique, the hihat firmware was constantly being read in the loop, while only the VCA was running, for a closed hihat circuit it was able to defuse the current through an additional method based on the bank decay setting. This basically makes the hihat sound different in every hit.
CEM VCF filters: unlike the very first LM-1 units released, the later versions were filtering voices with a bass frequency to minimize the remaining 8-bit noise using the CEM 3320 VCF configured as a low-pass filter without resonance. The frequency of the VCF CV was formed by the circuit in such a way that the transients pass relatively unfiltered. VProm allows you to fine tune the CV pulse or completely bypass the filter, it’s useful when the voice is set very low or if you want to replace the “Bass” slot with another EPROM that does not require filtering.
Separate pitch adjustment: this is one of the coolest features of the LM-1, allowing you to tune any voice to a specific frequency for a wide range of sounds. EPROM data was read by one byte at a time using a counter whose speed was monitored by a relatively stable oscillator, then the speed of reading the counters could depend on external tuning cameras in a limited range of + or – 1 octave. This tuning range can be changed, and VProm provides a useful wide range of steps from 1000 Hz to 44,100 Hz and everything that is between them based on the real mode. (the reserve was about 12048 – 30303 Hz.).
Individual outputs: The LM-1 has separate outputs for each voice, since VProm. For each voice in the DAW, you can select ALL-1 Stereo channels or Individual channels.
Speed control: you can limit yourself to only two levels of speed or use the entire MIDI speed range for convenience.
GUI and automation: the graphical user interface has original trigger buttons for quickly listening and controlling all aspects of the drum machine, most parameters such as volume and pitch controls can be learned by MIDI to control changes from any external MIDI equipment.
Loading external EPROM data: VProm provides the ability to replace all voices with external compatible 8-bit data with combined EPROM data. Which opens the machine for the samples LINNDRUM (LM-2), LINN 9000, DMX, DX, DRUMTRACKS, etc. Or even loads its own order. You can switch between configurable downloadable and spare EPROMs on the fly. VProm Supports the following types and size EPROM files (.bin):
2716 (2048_Bytes) 2K.
2732 (4096_Bytes) 4K.
2764 (8192_Bytes) 8K.
27128 (16384_Bytes) 16K.
27256 (32768_Bytes) 32K.
LINN LM-1 Sequencer:
It was not necessary to simulate the LM-1 sequencer, because regardless of all the urban legends about it, it’s basically 48 questions of PPQN (momentum per quarter note). Modern sequencers and DAWs have a finer resolution, usually around 960 PPQN or higher, it simply means that the same bit with some swings will not exactly match 960 or 48 PPQN … It’s easy to do to export your rhythm to MIDI a 48 PPQN and import it back. A full technical explanation is available in the VProm manual.
VProm version 2.0 has some improvements and changes compared to version 1.0
