Re: DX-100 patch editor / librarian for Mac os 10.7 or 10.9?

and the old 4op DX21 has a simple performance mode, which allows layering of 2 sounds - it makes it a much more powerful instrument than the DX100, DX9, and the DX27. It is able to produce wide, detuned stereo sounds, that even


Re: DX-100 patch editor / librarian for Mac os 10.7 or 10.9?

 

I see.? I didn't realise that.? My TX81Z has it, yes.? I've never tried it though.

I'm more of a woodwind and brass person, really.? One instrument sound at a time is enough, for the likes of me :)

Re: DX-100 patch editor / librarian for Mac os 10.7 or 10.9?

 

DX100 does not have performance mode. Several synths from the 4op FM family (fb01, tx81z, dx11, ys200, v50) did, but not the cute little dx100.

Hi Teo,

I like the sound of Harpsichord2 better for the right hand notes, but Harpsichord Low sounds better for the bass notes in those recordings, I agree.? You could probably make a Performance patch with a keyboard split, to combine the two, but it might be simpler to just use one patch on each DX100, if you're playing two at once.

You can, in theory, make something a bit more like your PSR patch using a Performance patch too.? It's something I've never done though, and I don't know the details of how to do it on a DX100.? Using the front panel for editing one ought to be an option, if all else fails.? There aren't as many parameters to set as when you edit a voice.

I'm not so keen on the reverb, but I rarely get on with reverbs.? I've bought a couple of different guitar pedal ones and I'm not happy with those either.? They always sound too fake, to me.? When I've tried one with a guitar it just got in the way of hearing what I was playing, properly.

Re: Early TX816 capacitors

 

Thanks for your feedback, I will proceed according to your suggestions!


Re: DX-100 patch editor / librarian for Mac os 10.7 or 10.9?

 

Hi Andy et all,

I'm new (this time) to how to use these groups, I'll learn better how to see who I'm replying to and who to thank for their time.

I want to get into some tweaking of sounds like you mentioned keyboard scaling, but at this second I'm warming up to how well I can play these baroque pieces with and without sustain pedal, and here today I can share some that have the left and right mix or lack of in mind. It's the 2 DX-100s "Freeboards" I call it.

I also don't know if I can attach 10MB a day into these groups or if that's too much memory. These files today are a Scarlatti piece I can't wait to really record but I'm seeing it this sound Harpsichord2 I found is better than the built in Harpsichord Low and Harpsichord High. My initial answer is no.

I might use Harpsichord2 on a song where harpsichord is ONLY in the higher notes, I like it's brightness but the lowest notes aren't anywhere as good as Harpsichord Low. Of course I feel bad trying to emulate a real instrument, go buy a harpsichord! Well, I'll be tweaking my organ sounds next, and trying out the breath controller on patches for solos! That'll be a blast on some songs!

I also have to apologize in advance, I am a time-bandit, I'll talk your ear off if you let me. This whole designing a way to perform 2 keyboards live while no pedals on the floor is a neat thing but so many issues! Y-Jacks into sustain pedal jacks, then 1 day I'll want to run them both MIDI and jam channel 10 percussion, I have a whole show setup with that I'll share later!

So I hope this is appropriate to share these - at least these are edited, no MAJOR mistakes, though none are the full song.







Inda says maybe too much reverb, I agree.. I'll likely use a bigger room like hall reverb but 30%. This also mixes the left and right nicely doesn't it! Like you said before, when I have 2 instruments going it could be quite the issue!

So I've decided the High&Low harpsichords sound better overall, meaning the low notes sound like a harpsichord I think. The Harpsichord2 has great sound though! If I just wanted a right hand part I might use it. I still have 2 or 3 Harpsichord patches I have to test - 1 is completely out of tune! I don't know why, I think it's called 1700Keyboard, more on that later.

My real questions today are: Can I just upload / attach these files into this group or will an admin frown at me at some point? I can upload them into my site Givnology.com but probably not direct linked like above "hotlinked" but my webpateexperience where they are now will get full soon doing this..

Second question, baroque patches! This is what I want, similar to "Chamber" on my Yamaha PSR 320 (I think) it works great for bass AND string section sounds!

That's totally unedited sorry! If I find great baroque orchestra sounds that or like Theorbo bass/guitar I'll be in 7th heaven!

Thanks for your time,
Teo

I have actually seen switching power supply designs that will not work properly with low-ESR capacitors.? The power IC manufacturer was using the higher resistance for stability in the feedback loop, IIRC.

That said, these designs all came out in the late '90s or early '00s, long after the TX816 was designed, so I don't think it's a problem here.? But it just goes to show:? if some phenomenon exists, however 'undesirable' to most, some designer somewhere will find a use for it!? ;-)

After your study of PSU schematics you will understand it’s not necessary.

They used two caps in series because on machines with voltage selector they are used separately when 100 V are selected. Then 200 V is enough reserve.

When 220 Volt is selected, they are connected in series, which makes their total value 235 uF, and voltage is doubled - 400 V. Which is similar to C9 value connected behind L2.

At least if I understand well capacitor math :-)?

C7 C8 - Marcon 200WV 470?F 85°C <<< shouldn't they be of a higher voltage to support the 230V operation?

I don’t know if it’s necessary to have low ESR caps for PSU, maybe somebody can answer this.

I would use 105 grades.

I will send schematics to your address.

110V is really 120V in many countries 120V RMS is 170V peak; 340V p-p . if the capacitor cannot get discharged in time.? Probably to cover for UL/CSA/TUV/etc. safety requirements.

You are welcome!


This article () says it means "Light & Music". Maybe SK and PK would be other companies or other divisions inside Yamaha.

It’s quite possible, PK is usually used for Portable Keyboards. But I think nowadays Yamaha has different internal structure.

Regarding the ID you're correct it seems to indicate a format and not an instrument thus explaining why it would change depending of the firmware's version (a newer firmware would support another SYX format etc…).

No, it is not changed - the SysEx data format stays the same even when new version of OS came. It would be a great confusion to change data format when OS version changes. Besides OS version changes were not publicly known and announced, only authorized serveice technicians were informed…?

This ID would be hexadecimal like many other data in the MIDI world (but still written in ASCII) so it's normal to have letters.

I suppose you wanted to say “binary” - MIDI world is not hexadecimal nor decimal nor ASCII. It is only transcribed that way for simplicity.?

And if you mean that this letter “A” as a part of four characters in the header is hexadecimal number, that’s wrong. It’s just ASCII code.
Number “A” in hex would have only four bits (binary 1010), but ASCII “A” in the header has one full byte - in hex it is 41 (binary 01000001). Am I right? Can you see the difference?


Regarding my TX the PSU is again in a very nice condition (no buldging/leaking caps nor tarnished solder near them) and I found that the big red wired jumper outside the PSU is actually the voltage selector! Plugged it would make it a 100V one, and unplugged a 220 (or 230V) one!

Great! Probably my TX's with voltage selector are slightly different concerning this red jumper. It’s longer time I did repairs and complete recapping of my TX's and TF's, so I don’t remember such details at all. Too many instruments I did in last years and still there’s a lot of others as they are aging, too.

I guessed that looking at the 400V capacitor (why out such a large value if your PSU is only 110V) and confirming that with the page 30 of the service manual.

Thanks for this info, but still it didn’t explain the meaning of LM.

Few additions to your info:
- header is not indicating the instrument. It is header of SysEx memory dump. So some relative instruments can use the same numbers.

- header is not for one instrument, but for data type. One and the same instrument can have different numbers for Voices, Performances, Multi, Drumset etc. etc. Opposite - different instruments can use the same numbers.

- four numbers are not the last 4 characters of header, it’s followed by two other letters designated type

- not always there are 4 numbers, I have found also 8A21, 8A26, 8A27

- not always there are numbers - sometimes they are replaced by letters (like DX7 II D/FD Fractional Scaling or Microtune)

- there can be added one number at the end if instrument has more data blocks of the same type (like TX81z System or Microtune)?

- not always there is LM__ - I have found instruments which have SK__ or PK__

Yamaha has been using this system around between 1986 - 1998, not on all machines. There were also other systems used in their instruments, sometimes even mixed in one instrument.

If you are interested in, here are some header numbers from my gear, and few others:
