How to type instructions for FTS for particular soft synths

Contents

ZynAddSubFX

You can get this free synth from: ZynAddSubFX. For the Windows installer go to the download page. Find the latest release with a windows installer. As of writing, 2.2.0 comes with the windows installer, but not yet 2.2.1.

ZASF is a synth with hidden capabilities. First of all - it seems to be able to play only one pitch bend at a time like many other synths. But you can get it to play on sixteen channels.

Receive notes on any number of channels

Change to the Advanced mode (from Misc). | Switch user interface mode).

Go to the place where it shows the channel number, and scroll through all the numbers, and click enabled for each one. It will then play on all the channels.

Open this file in ZASF to set it up like that for all sixteen midi channels: allchanns.xmz

After that you should be able to use it with FTS with the pitch bend retuning method like any other synth with sixteen channel type capabilities.

SCALA scale and keyboard map

ZASF is also capable of retuning to any scale with any keyboard mapping.

Click the Scales button in the advanced interface:

ZynAddSubFX scales.png

Then select Enable microtonal and enter the desired pitches and keyboard mapping. Or you can open any scale and keyboard mapping you have already.

Here is a scale and keyboard mapping to use with ZASF with the Lambdoma task.

Media:Lambdoma.kbm and Media:Lambdoma.scl

You can use it with the keyboard directly - except that the order of the rows running down diagonally to the right on the keyboard gets reversed - that's to do with how FTS deals with the note to scale mapping internally. See Media:Lambdoma.kbm and Media:Lambdoma.scl

Also, you can use it with ZASF and FTS with the option Out | Set Parts to play for Each Device | More | Treat Highl. as already tuned.

For some reason, if you save all the parameters from ZASF, exit from the program, start it up and reopen all the parameters it seems to get confused about the previously loaded scale - displayed okay but not played correctly - so you have to reload the scale every time you start up the program. So - I did a parameters for ZASF for Lambdoma simply tuned but you need to reload the scale every time you use it, but everything else is okay see lambdoma_simply_tuned.xmz attached.

Garritan Personal Orchestra

A lot of composers also use the Garritan personal orchestra.

Keyswitches

The GPO instruments use keyswitches - notes below the playable range of the instrument which don't actually play sounds, but instead, change the performance style.

You have to tell FTS about those, to let them through unchanged. Otherwise it will try to play them as retuned notes, - changing the midi note sent, adding pitch bends, and so forth, which will change the effect of the keyswitch`.

You do that using More Midi In options - For rarer occasions (ctrl+92)

With the full version of GPO, Check the box labelled "Only retune Midi in notes between" and then use "12" and "127" as the bounds. Set the pulldown list marked "Outside range:" to the value "Send on" or "Send to all channels for part"

With the Lite version of GPO, the key switches depend on the instrument. So use Retuning range for parts (ctrl+193) and set that window up to ignore notes below the instruments playable range (e.g. below 54 for the Finale Lite "trumpet").

pitch bend ranges

The pitch bend ranges in GPO depend on the instrument - some have a pitch bend range of 12 semitones and some the standard pitch bend range of 2 semitones, and some only 1 semitone. So you have to set the pitch bend range to depend on the part, and set the pitch bend range for each part depending on the instrument used.

You do that using [Window 191 | Pitch Bend Range and Multiplier for Part (ctrl+191)]]

For the pitch bend ranges to use, see Pitch Bend Ranges and Other GPO Information

Rick McGowan has written a tutorial on how to use GPO with FTS to retune large orchestral scores - which involves use of the Out Devices for Midi In Devices (ctrl+192) window.

His tutorial also assumes you use FTS with tuning tables - i.e. load tuning tables to retune FTS. You can as easily use scala scales or construct the scales in FTS itself and configure the pitch of the 1/1 in FTS. So, if you are already accustomed to working with FTS in that fashion, there is no need to change your way of working for GPO. Just ignore the instructions relating to .tun tables.

FTS-How-To - microtuning the orchestra

Example mp3s

See Rick McGowan's Audio Examples

Giga Studio

Giga was the pioneer in the field of software samplers - streaming the sounds directly from the hard disk to permit use of entire recordings of single notes instead of the looped short sections of waves used previously.

You may be able to get the Lite version Gigasampler for free with some soundcards if you shop around. Giga Studio costs more and has more features (one can upgrade to it from Gigasampler)

You need to buy extra sounds for giga only a few ones come with it. These can be quite costly, generally $100s right up to $1000s. I use Dan Dean's solo strings and I highly recommend that one for string instruments.

The web site is here: Gigasampler / GigaStudio

Pitch bend range for Giga

Many of the instruments you can get for Giga have the pitch bend range locked to 0 cents. So in order to play in any of the tunings, you want to change this to the GM default of 2 semitones.

It is easy to tell if this is so - just try playing, say, an ascending scale in FTS in some low ET, such as 31-tet - click the Play Scalebutton in FTS. If you hear repeated notes, then the pitch bend range is locked to 0 in Giga.

To unlock this, load your instrument in Giga, and go to Edit Instument. Then in the Instrument Editor, go to the Instrument Bank, right click on each instrument in turn, look for the Pitch bend (semitones)field, and set this to 2.

Key switches

If the Giga instrument you are using requires keyswitches to change the performance style, you need to tell FTS to send those notes on unchanged. Use Retuning range for parts (ctrl+193) and set that window up to ignore notes below the instruments playable range for any part that uses key switches.

Example mp3s

Here are a few mp3s of tunes made using FTS and Giga:

For other tips, see FTS | Help | Using FTS with Giga .

The FM7

The FM7 is great for new sounds, and extremely accurate pitch wise. The demo version, which will only play in twelve equal as it will only accept one pitch bend at a time. Try out the demo to see if you like the sounds, then when you buy it you will be able to play it in any of the tunings from FTS by selecting Out | Use MTS Tuning programs . This doesn't work with the demo because FTS retunes it using MTS sysexes, which are disabled in the demo version of the FM7.

It has some really wild sounds - try out http://mp3.com.au/ScienceFriction/ and http://mp3.com.au/NavigatingThePacific/

The FM7 is monotimbral - only plays one voice at a time (I know it sounds as if it is multi-timbral from the Navigating the Pacific - but that is just a single really wild patch - all the notes are played on the same instrument).

To play several instruments at once, you can start up several copies of it and then set FTS to relay to each of those separately - easiest done using a virtual midi cable.

CSound

CSound is a sound synthesis programming language, with many instruments developed for it. See the wikipedia entry on CSound.

It has generally been regarded as rather techy. But FTS has incorporated automated orchestra and score building. This makes using CSound instruments in your recordings as easy as selecting them from a drop list. You can use them to render your midi recordings or fractal tunes directly to audio.

CSound instruments can also be designed to respond to midi in real time. So using this, you can also play the Csound instruments in real time with the help of CSoundAV.

FTS comes with a number of pre-defined CSound instruments, and techy users can easily add more to the list.

See the CSound page of this site for more information.

Quicktime

You can select Quicktime from the Out menu in Fractal Tune Smithy (new feature). Quicktime is not normally accessible in this way in Windows. I added it in as a way to let you preview what the tunes would sound like, and to give an alternative (free) way of playing the Quicktime instruments for those who wish to use them in real time.

Quicktime selected in the Out menu in FTS is best used to preview fractal tunes as the timing can be a bit irregular. You can use Record to File options | Play as Html to hear your finished piece. See Using FTS with Quicktime

A nice thing about Quicktime is that it lets you have more than 15 melodic channels, which gives a way to get more "pitch polyphony". FTS exploits that by adding up to two "Quicktime" devices to the Out menu. You can play some of your parts on one of them and some on another by using the Out | Multiple Out Devices - Selected parts window.

You don't normally see Quicktime on the out menu of programs. The Roland however does add itself. If you want to use it on programs like Media Player that don't have an Out menu you can change what you want to use as the standard midi output device via Start | Settings | Control Panel | Multimedia | Midi

However, on Windows anyway, it seems that Quicktime works best when playing the tunes as midi clips - the timing can sometimes be a little erratic when it is used to play notes in real time "as they come". It has to be done in real time in FTS even for the fractal tunes, because the user can change the notes and the speed while the tune is playing. How well it plays in real time may depend on your setup.

To help Quicktime users, there's an option to save your current tune and show it in a web page and so you can play it that way, after previewing it in FTS. You do it via Files | Midi File Options | Save and Show as Html . This option can also be useful as a way to preview midi clilps in QT if you have it only in use on your system as a web page plug in (and haven't associated it with midi files).

When you play the notes from the music or PC keyboard QT seems to work reasonably well - with a small amount of latency of course.

Quicktime also makes pitch bend glides when you use it in real; time. It happens if you apply an "instant" pitch bend immediately before a note.

This is quite common with soft synths, but can be dealt with. See pitch glides (below) in the section on Limitations of some soft synths The first time you use FTS with QuickTimeyou will get a message about this. It offers to set a delay of 250 ms. You can change this from Out | Options | Out (menu) | Midi Out Timing - but need to set a delay there to avoid the message - you can set it to 0 ms if you don't need one.

The Roland soft synth

This uses the same sound set as Quicktime, but without the timing issues when played in real time. It is quite hard to obtain these days, but you can buy it at PG Music (you have to purchase another program as well).

The Roland Sound Canvas needs a modern PC - but any PC from 2000 or so onwards should be plenty fast enough, so this only needs to be checked if you have a really old PC.

The Roland will let you save midi files directly to audio format, which is neat.

I hear pitch artefacts - what can I do about them?

There are various reasons why this may happen. See Pitch artefacts for the details of what may happen, and what you can do about it.
