Instrument Overview

According to the original creators, Streetly Electronics, the true sound of a ‘Melly’ is the combination of several factors.

Firstly, it’s the EMI tape, which they claim is the best tape formula in the world.

Secondly, Martin Smith of Streetly insists “The sound of a Melly is not the Master Tapes, it’s the sound from the recordings in IBC studios edited to Master Tapes, edited to Working Masters, edited to Protection Copies, edited to the actual tapes on your machine.”

Finally, and crucially, it’s both of these things played across a properly aligned tape-head and recorded via an instrument’s preamp.

So, with these ground rules in mind and under the skill and guidance of Martin and John Bradley, we are pleased to release the final volume in the Streetly musical expansion pack trilogy, The Streetly Tapes - Vol 3 Expansion Pack for M-Tron Pro.

As per the previous Vol 1 & Vol 2, all the sounds here were curated by Martin Smith from the Streetly archives and then recorded via the Skellotron, a bare bones M400 built to allow detailed adjustment of every component including the azimuth alignment of each tape-head. Once captured and cross referenced against an M4000 the sounds were sent to us at GForce for their conversion into the M-Tron Pro file format.

This selection was taken back to Streetly Electronics where John conducted A/B tests against their magnificent M4000 and only when Martin and John were satisfied was the set of tapes given to our patch designers for final patch creation.

The Original Instrument

While we love and admire the engineering of the original hardware machines, we also think hardware and good software should sit side-by-side. Because although the hardware versus software debate still rages, ad nauseam, the simple truth is that there's no definitive answer as to which is best. Just as there is good and bad hardware, there is good and bad software and the answer to this conundrum will depend on all manner of things including your personal perspective, available space, your technical savvy, your preferred working environment and of course your finances.

For example, do the majority of musicians looking for ‘that sound’ really care to maintain a forty-plus year old instrument, sourcing rare parts when they wear out or break?

Naturally we care, because we feel that we’re custodians of these instruments and while many other software companies simply hire-in instruments to record or model, we consider this bad practice. In our opinion good practice is when you've lived with and loved the original instrument's character and foibles for a considerable time before beginning any emulative process. Because, then and only then, do you stand a chance of capturing some of the instrument's soul and character within the software alchemy.

It's a simple dogma but you'd be surprised at how many software companies ignore this in favour of marketing hyperbole. Indeed, when we explained our philosophy to the marketing director of one such company, he said "No one really cares" and strolled off to no doubt perpetrate more marketing myths.

For us that fundamental understanding and love for an instrument is what really matters when trying to transplant its character. You see, we can tell the difference between good or bad, lazy or indifferent, marketing bullshit versus a real love for the authentic, because we’ve been immersed in these instruments for over 30 years. And in the case of Streetly, over 50 years!

But ponder this - while we’ve thrown countless bags of money at the purchasing and maintenance of all manner of tape replay instruments from Chamberlin’s to Mellotrons, we’re the exception. We’re committed (some would say ‘certifiable’) and we do it so that you don’t have to.

If you want an M400 plus all the tapes we supplied with the M-Tron Pro, you'd be looking at £20,000 plus, as opposed to the M-Tron Pro's £140. Likewise, if you wanted to buy the physical tape frames of a Streetly Tapes Volume for your original M400 you’d be looking at a price tag of at least £5,000, whereas at 1% of that each Streetly Tape Volume represent amazing value for money.

It’s something worth bearing in mind the next time that someone tells you that hardware is better than software.
