The VLINN LM-1 DRUM VST provides the closest experience to the real thing because it is not based on samples, instead it accurately models the clocks and counters that reads EPROMS memory feeding the AM6070 DACs to decode the EPROMS data in realtime, models the CEM 3320 filters with tweakable control over the CV pulses shapes to let more or less transient pass through unfiltered or completely bypass them, special hihat circuitry and VCA providing different hihat sound on each trigger and decay control, separate tuning for all voices with already a wider range without tweaking the electronics...separate outputs for your DAW, velocity handling etc...You will maintain that raw sound at every tune! On top of the cake 7+1 voices can be replaced with external EPROM data like on a real machine...Opening up a whole new range of sound, still being processed by the circuitry.

VLINN DRUM VST does not emulate the LM-1 Drum Computer Sequencer & OS because as Roger Linn himself has stated, it was only a 48PPQ resolution thing... See explanation below about the sequencer.
It does not in any way imply Roger Linn's permission or endorsement of the VLINN product.
However I have a kind permission from Roger Linn to use the LM-1 original samples binaries in VLINN for convenience.
VLINN was first made for personal use and will be available with a donation (starting at 15 €).
The Linn was THE killer drum machine in town back in the 80's it was also the first that include real drum samples! The Linn LM-1 Drum Computer was created by Roger Linn. He used samples of acoustic drum sounds recorded on the fly with some basic hardware. The fact that they were recorded raw with a custom made ADC makes them cut better in a mix than anything available at the time, they sounded so great that they become an alternative to the analog drum sounds of the 80's drum machines.. to this day the unique sound of that machine is highly regarded and only using samples of an LM-1 output cannot reproduce the wide range of sounds this machine can produce. The DAC in use in here and he whole circuitry stands next to the samples characters in that unique sounding team.
The LM-1 is an historical piece of gear that has a place in the sound of the 80's era. Only around 500 of these things are out there so don't count on finding a working one easily or for cheap. It has been used by major acts like: Prince, Phil Collins, Thompson Twins, Stevie Wonder, Gary Numan, Depeche Mode, The Human League, Jean-Michel Jarre, Vangelis, John Carpenter, Todd Rundgren,The Art of Noise... The Machine was made by a musician for musicians and I tried to stick to that standard :) So as there were no accurate VST for that legend out there...
I had to make the VLINN!
LINN LM-1 SEQUENCER?
It was not needed to model the LM-1 sequencer because regardless of all the urban legends about it, it is mainly a 48PPQN (pulse per quarter note) resolution thing.
Modern DAWs features a finer resolution usually around 960PPQN or higher, this simply means that the same beat with some swing will not groove exactly the same at 960 or 48PPQN... An easy thing to do is to export your beat in MIDI a 48PPQN and import it back :)

VLINN DRUM FEATURES
AM6070 MODELED REAL TIME DAC DECODING
Following the exact datasheet decode table for 8bit companded incoming DATA. The real LM-1 nasty griddy sound at every pitch, like the real thing, forget resampling or tuning crappy samples packs which will always sound dull at lower pitches!
HIHAT DATA LOOPING & VCA
The LM-1 Hihat circuitry was pretty unique, the hihat proms were read constantly in a loop while only a VCA was triggered, for closed hihat the circuitry had the ability to discharge the current through an additional way based on the decay pot setting. This basically makes the hihat sounding different on every hit.
CEM 3320 Filters
Unlike the very first produced LM-1, some Voices with Bass frequency content were filtered to minimize the remaining 8bit noise, using a VCF configured as a lowpass filter with no resonance. The CV frequency of the VCF was shaped by the circuitry in a way that lets the transients pass through relatively unfiltered. The VLINN lets you fine tune the CV pulse or completely bypass the filter, this is useful when a voice is tuned very low or if you want to replace a "Bass" slot with another EPROM that doesn't require filtering.
SEPARATE PITCH TUNING
This is one of the coolest feature of the LM-1, letting you tune any voice to a particular frequency for a wide range of sounds.
The PROMS data were read one byte at the time by a counter which speed was controlled by a relatively stable oscillator, the counters reading speed could then be affected by the external tuning pots in a limited range, + or - 1 Octave.
This tuning range can be tweaked and the VLINN provides a useful wide range of pitch from 1000Hz to 44100Hz and anything in between based on a real mod.(see manual)
(stock was 12048 - 30303Hz.)
The LM-1 features separate outputs for every voices, so as the VLINN.
You can choose from ALL to 1 Stereo Channel or Separate Channels for each voice.
You can limit yourself to only 2 velocity levels or use the full range of MIDI velocity for convenience.
GUI & AUTOMATION
The GUI features the original trigger buttons for kick listening and controls over every aspect of the Drum Machine, most of the parameters like volume and pitch knobs can be MIDI learned and controlled by an external MIDI Hardware.
LOADING EXTERNAL EPROMS DATA
The VLINN provides the ability to replace some voices with external compatible 8bit companded EPROM data. Which opens up the machine to LINNDRUM (LM-2), LINN 9000, DMX, DX, DRUMTRACKS etc... samples or even load your own custom made. You can switch between custom loaded and stock EPROMS on the fly.
VLINN Supports the following type and size EPROMS binaries (.bin)
