Put Legendary Mellotron Sounds into Your Studio!

The GForce M-Tron Pro is a spot-on emulation of the legendary Mellotron, the tape-based keyboard heard on recordings by such artists as The Beatles, David Bowie, Led Zeppelin, and Radiohead. M-Tron Pro offers a huge 3.5GB sound library with more than 160 tape banks, and it includes 19 of the first M-Tron tape banks, all remastered at the acclaimed Abbey Road Studios. You also get 45 new sample sets and more than 500 specially created patches. For Mellotron sound with digital ease, you need GForce's M-Tron Pro.

From the flutes on the legendary introduction to The Beatles' "Strawberry Fields Forever" to tracks from The Moody Blues, David Bowie, and The Rolling Stones to the modern sounds of The Flaming Lips, Nine Inch Nails, Modest Mouse, Muse, U2, Sigur Ros, and more, there's no question that the sound of the Mellotron is a deep part of music history. Now, you can experience that tape-based playback sonic experience for yourself - and with 100%-digital convenience - with GForce's M-Tron Pro.

Of its massive 160+ tape-bank library, M-Tron Pro gives you 45 brand-new tape banks not found on GForce's original Mellotron. What's more, 19 tapes from the M-Tron have been remastered at London's legendary Abbey Road Studios for the ultimate in sound quality. In total, there are over 3.5GB of world-class samples.

In addition to its 160+ tape banks, GForce's M-Tron Pro boasts more than 500 patches, many custom-designed by world-class recording artists and programmers, so you have instant access to a diverse sonic palette.

G-Force M-Tron Pro offers up to 35 notes, each individually sampled. It also supports dual-layer and split-keyboard operation in addition to MIDI Learn. All of this functionality adds up to a wealth of control over its 29 parameters per layer, including ensemble and delay effects; lowpass, bandpass, and highpass filters; and tape-based effects, such as reverse and half speed. What's more, M-Tron Pro can operate standalone, so it's easy to quickly load it up on your laptop and perform with a MIDI controller onstage.

Dream come true

Growing up in the late 60's/early 70's I was always drawn to the sound of the Mellotron. It has a mystical, dreamy quality to it that seems timeless. I've tried lots of Mellotron emulations and have been impressed by some, but the GForce M-Tron Pro is the real thing. Better than the real thing actually since you don't have to deal with the problems of the physical hardware. The amount of presets included is truly mind-blowing, some are by Rick Wakeman! I can't recommend this instrument enough!

Mtron Pro

I was owner of the original version of this product. This release is worth the money as it is far superior to the original release. It works quite well. Latency is not an issue and the sounds are terrific. I have had several original Mellotrons including a double Tron. I also used to have a Birotron. Whuile the originals bear some mysterious appeal, mlstly for the novelty of the instrument, this rendition and overall paradigm is far superior for recording and playing live. Hassle factor of this compared to the originals not even a close comparison. The sounds are infinately better to work with in this rendition, and apart from the visual of a broken back and a large thing that could easily be a time machine, again the Mtron is superior.

I absolutely LOVE this plugin!

GForce has really thought this one through! M-Tron comes with so many amazing sounds and having the ability to layer them really makes the possibilities endless. To make things even better, you can reverse and/or use half-speed on all the sounds. It's awesome! And going one step beyond that, you can spend another $39 and get the Optigan sounds (GForce calls these OptiTron) to add to your M-Tron library - in their own category listing. Very well done! :) Within minutes after purchasing the Electronic Delivery version I had an email from Sweetwater with all the information I needed to download my software. I was up and running in a short amount of time. Keep in mind that downloading this plugin will take a little time as the sounds are over 3GB.


I have nothing but good things to say about this product, the sales-people, and the support. I LOVE this product. Andy Bitler is the best music sales-human I have ever dealt with (ever!), and John from Mac/Tech support was AMAZING! This company rocks and between the Logic9 I purchased and this incredible plug in, I am wasting precious hours that I should be devoting to studies to the wonderful world of Mellotrons. Thank you to BOTH of you so much! OK, getting past the hero worship, I would like to see Sweetwater add a functionality to their customer service. Please add a "marker" so that we know where we are at when waiting on the phone help. I did lose almost an hour of Cell minutes, when I could have just either left a message for a callback, or B.) entered an email form with the appropriate info for a callback. This is small potatoes compared to the incredible value and service I get with Sweetwater as a whole. This is one of the BEST companies I have ever worked with!

An instrument in itself.

There are a LOT of mellotron smple sets out there on the market, but the feature set on the M-tron sets it apart from the others. The capability to reverse sounds, adjust the starting-points of sounds, combine sounds and tweak effects all within the interface make the M-Tron a unique instrument that allows you to harnesses the vintage Mellotron and bring it into another realm if you want to. I had a samll problem installing it due to a corrupt font file, but G-force support replied to my support inquiry within minutes and sent me a file that remedied the situation.All in all I am more than pleased with the M-tron. It is inspiring in a way that I don't think would be possible with a standard sample set in a generic sample interface. After mapping your MIDI controller to the essential functions it truly feels like an instrument. It is fun to record songs totally embellishing the lush rythems and lo-fi instrument sounds in the M-tron, but it is truly useful to use the M-tron in a subtle way to add some mystery and lo-fi goodness to an other wise contemporary track.If you are in the market for a Mellotron clone or sample set you can't go wronge with this one. It may not be the most complete set of samples on the market, but it is still extensive and is quite an inspiring intrument to boot.

What do The Beatles, the Moody Blues, and Marilyn Manson all have in common? They all used Mellotrons on their albums! All of the classic sounds you need are all built in to this instrument. I gurantee you will love it, I do.
