Reaktor 5 or lower

DESCRIPTION

...new at least in Reaktor.

The basic idea was to realise the equation
e = A*sin(a*t + I * sin(b*t))
as it was given by John M. Chowning ,the 'inventor' of FM synthesis, for a frequency-modulated wave 'e'.

The sound differs from usual Reaktor-FM-synths ( the only exeption I know of is 'sy-fm') for the synthesis method is rather 'phase modulation' than 'frequency modulation'. The difference should be audible when more than two operators are stacked or when feedback is applied.

Features ;-):
4 Operator FM synthesis
8 Waveforms
Keyboard level scaling
Keyboard time scaling
Ratio coarse control with special non-integer ratios + ratio fine control
Oscillator linear detune
8 algorithms
Pitch Envelope Generator

This synth does not offer ultimate flexibility, but is - hopefully - easy to program.
It does not offer the rich sound of an 6-OP-FM-Synth, but some interesting sounds are possible.



The snapshots are not meant as a set of fully featured presets, there are some repetitions,
some sounds are not finished, and some are most probably useless. I leave it to you to alter or to delete those ;-).

Unfortunately quite CPU hungry.

Well, you guess it, this .ins was inspired by a certain piece of hardware. ;-)

Very good! While I do miss an operator matrix (a la Linplug's "Octopus"), the algorithm section is plenty robust. I also like the fact that it has LFO options and is already friendly with the mod-wheel. I have been trying to learn FM synthesis lately, and this Reaktor ensemble is an amazing tool for the job. Since this shockingly isn't hardware, one could easily duplicate it and cause this beast to offer some uber-thick pads (FM pads are sexy, but rare).

very clean but as you say yourself, quite cpu hungry

Somehow I've overlooked this truly excellent upload... set to 6 bits depth it replaces my trusty old DX9 that I'm about to give away...

Apart from the PingPong Delay, can we say this ensemble is nearly identical to the actual DX11 structure? This would make learning how to program the synth much easier. Great ensemble - thanks for the upload!

One of the cleanest sounding FM synths I have ever heard!

Like Phil Durrant said. this is a very significant and important upload. i love this S Y N T H to death. when it comes to fm synthesis in reaktor, this ensemble is it ! Its killer for detroit techno and chicago house. It has it written all over it. The fm routing / algorithm section is a very elaborate reaktor structure. This S Y N T H is very practical, and very useful. It sounds dam close to an actual yamaha dx 100. 10 / 10 !

i too tend to be impressed by good snaps. this has many. i have a Yamaha TX802, so i like FM synth sounds. especially harsh-yet-musical sounds. this ensemble is great. it has a lot of flexibility. more importantly, it's easy to adjust the parameters and get an idea of what you're doing by listening as you adjust. the routing algorithm images are helpful, too. i would like to see more dynamics used in the snaps, but that's my only critical comment. great work!

Like everyone else says, the real standout for this ensemble is the sound. Great!

Very nice sounding. Like you say, it's quite cpu hungry.

I have a DX 100 and had a DX 7 and tx 81z. This is the first software emulation that comes near to the sounds of these old harsh monsters. Thank you

Flawless interface. . . just the right balance between slickness, efficiency, and usability. You've given the rest of the world a chance to see how a TX81Z through an FM-lover's eyes. Oh, and it happens to sound fantastic too.

Really nice FM sounds. It could have a little bit more dynamics.

An FM buffet, all the sounds you can eat up.

I am sorry I sold my TX81Z. Not anymore. This thing is a dream machine. Thanks.

well, if u wanna analyse the structure, you'll have problems to find the structure windows, they're spread overall. But the synth is great, one of the best FM synths ever seen!

Fantastic.... plain and simple.... I have now gotten a chance to really work with this and I must say it's quite extraordinary.... you have my respect and thanx

Exceptional sound! Really great sounding snapshots. I have NI FM7, a DX7, a TX802, and a FS1R, this thing really holds it's own against all these. This is truly an outstanding FM beast ! ! THANK YOU !

this is a very significant and important upload. this is the reaktor synth that i will use for FM. have a look at how the different waves have been made. yes, quite different to any other synth that i have seen in reaktor. the pre-sets are classic tx 81Z. if that puts you off (kev hopper) this has plenty of scope to programme your own. thank you so much for this, it is what i hoped someone would do some day.

quite cool! two things: the envelopes are way too easy to understand, what happened to the classic, mysterious 1 to 37 reverse angle way that the real thing measures them with? also, it's not heavy enough.

I must admit, I'm lazy... so I tend to judge a book by its cover (i.e. a .ens by its snaps)... this one is excellent.... a lot of really good patches here. Now if I could just find the time to "look under the hood".... great work -- a 10 here.

Very nice, if you are into FM, or nasty if you are not (I'm into everything). Either way this is a really excellent implementation of the 'dx' concept. Good programming of the snaps as well. I can only hope that you have plans to add the remaining ops ;)
