JV-1010 volume issue

[Yasoo]

I'm getting radical volumne changes between different patches. Anyone notice this? Is this by design? So, I might have a piano patch selected and then switch to a nylon guitar and the volume of the nylon guitar is whisper quiet compared to the piano. I'm really new to using this equipment so I don't know what to think about this, but it seems like a flaw.

I've never noticed this with my unit. It may be a defect. Do you have the 1010 hooked up to an external sequencer? If so, could be differences in volume settings there. You can also set the volumes for each patch either via Soundiver, or externally (although these you lose these changes when you turn the unit off).

Would you mind checking a particular patch out? In Preset-B, patch 12 (Homey Bass) seems quieter than the surrounding patches. Also, in Preset-B, patch 13 (Finger Bass), if I play this patch with really fast notes over and over, eventually they stop producing audio. Not until I completely release all keys and start playing again. Do you notice this?

To do the update, read the readme file...

Updating the JV-1010 Operating System from Standard MIDI Files

Use the following procedure to update the JV-1010 to the
latest system version. The updated software is provided as
15 Standard MIDI Files, on a DOS or Macintosh formatted disk.

The tools required are:
* MIDI sequencer (software or hardware) that can load DOS or
Macintosh Standard MIDI Files
* MIDI cable
* JV-1010
* JV-1010 System Software update disk

Update Procedure
1) Power off the JV-1010 and connect the MIDI OUT port of the
sequencer to the MIDI IN port of the JV-1010.
2) Rotate the PART dial to select 14, then rotate the
CATEGORY dial to select Guitar/Bass.
3) Power on the JV-1010 while holding down VOLUME and VALUE.
4) After 3 seconds, release the dials and then press VOLUME
again. The display should read "nid."
5) Play all Standard MIDI Files from the MIDI sequencer in
sequential order.
6) After all SMF's have been played, power off. The system
software of the JV-1010 has now been updated.

You should reset the JV-1010 after it is updated:

**Warning: When you reset the JV-1010, all user parameters
will be erased and set to the factory settings.**

1) Power on the JV-1010
2) Press the VALUE dial to select any mode except PATCH mode.
3) While holding VOLUME, press VALUE.
4) Rotate the CATEGORY dial to select Piano. The screen will
display "Fct."
5) Press VALUE, the screen will display "Sur."
6) Press VALUE again to perform the factory reset.

Volume changes between patches is fairly normal. When I setup my keyboards for live rigs I had to do a lot of volume matching for the patches I would be using.

I did read those instructions. I was wondering if I had to set a channel in my sequencer. When I open the midi files they are set to "none". So I'm not sure if the info made it to the 1010. Nothing on the 1010 acted like it was receiving info.

Thanks for the info. I think they set up some of these patches to show us the different features of the synth. I think I can just load the quieter ones into a user bank and increase the volume using SoundDiver. However, I can't figure out which parameter makes it so that repeated fast playing where notes overlap results in the sound dying out until I release all keys and start playing again. Do you understand this phenomenon and why it happens?

I would assume you need to send out on channel 14...

That is related to the Polyphony of a keyboard. That means how many notes it can play at once. When you layer several sounds each one takes up a voice of polyphony for every key pressed. If you have 4 sounds layered and hit one note you are using 4 voices. If you hit some big chords and play 7 notes you are using up 28 voices. If you hold the sustain pedal and hit the chord twice you are using up 56 voices.

Since many keyboards only offer 32 or 64 voice polyphony you can use them up quickly. You can imagine how hard it was in the early 80's when most keyboards only had 8-16 voice polyphony.

Thanks TexRoadKill.
