yeah, this was awesome. that A00 trick is a great idea, I didn't realize how cool it was until I tried it.
However, for what he used it for, it would've been much more compact to define a groove and just have one transpose value on each row. So if your chord is 00, 00, 00, 00, 03, 03, 03, 03, 05, 05, 05, 05, 07, 07, 07, 07, 0A, 0A, 0A, 0A, 0E, 0E, 0E, 0E what yo can actually do is just enter 00, 03, 05, 07, 0A, 0E and use a groove which just has 4 in it. Use the G command in the table to activate that groove. That will wait 4 ticks between every step.
What's more, you can use this to easily make groovy chords by entering a groove 5,3,4,2
I didn't watch the video, but there is no reason why you need an on/off switch that I could think of!
maybe to prevent extra noise? my Expansion mod makes some nasty buzz and wine when it isnt in use. As soon as i load a nsf it clears up but during the menu screen its pretty nasty. when i unplug the wire the sound goes away... i dont know.
i think i'll do the mod without the switch and then if i notice that noise, i might install it afterwards. good to know though!
but what if i wanted it to come out of a separate jack and not the original?
It would be no different than the mod you already did.
you're really being unbelievably helpful. thank you so much.
my final question - why would you want to install an on/off switch for it like the guy in the video does? is there anything wrong with just having it on all the time?
To be specific, it outputs the expansion audio out on a pin that is re-routed back in on another pin, and 47k seems to be the accepted standard for the level of resistance needed to get an acceptable volume from the expansion chip sounds.
right now i have my nes "stereo" modded, so that the samples/noise and the pulses/triangle get their own outputs.
you're saying i could have a third output next to those that just outputs the expansion chip sounds?
The NES itself can't support expansion audio without a modification. You need to reroute the audio by connecting two pins with a 47k resistor-
Watch from 2:30 - 3:00. That's pretty much all you need to see, the rest is extra because he puts in a couple other things that aren't required to simply get it working.
are you saying that if i do this extremely simple mod then i will be able to play NSF files on my powerpak that take advantage of the vrc6?
i just watched this last night and i learned so much. i didn't know you could use the A command to make extra long tables. i've been very intimidated by a lot of the details of the WAV channel. i had no idea that you could control the K command. everyone should share some tricks/sav files!
this is definitely inspiring me to try to step up my game. very very cool!
The idea is for the code to go into the 128K/256K/perhaps larger Flash chip, and leave the battery RAM open for the code to use. The older design before these Flash chips was to use battery RAM (that's how all my current carts work).
And the PC-to-NES cable is as simple as it comes. It's basically just a USB-to-serial cable connected to the controller port, with the NES doing a software-based UART running at 5.7 KB/sec. And yes, the NES can send data back to the PC. One interesting program I've made using this link is an NSF player that runs on the PC, but sends the sound chip writes to the NES for more authentic sound (and even suppots DMC samples).
does this mean you could use a computer to sync an NES and LSDJ via an arduinoboy?
Would it be possible to make use of the additional controller port on the NES? If you modified a controller, you could use the various inputs to control the syncing. It wouldn't be too hard to splice an NES controller and a DMG link cable together. I'm not sure how LSDJ utiluzes the link cable for syncing, and you'd probably need a bit of simple electronics to get it to trigger the buttom presses on the NES, but this seems like a simple enough solution.
The same principal could be used for various control situations.
Not sure, i had nothing to do with that side of things when I was working on this with Batsly Adams.
The NTRQ sync (master) was sending pulses out of the second controller port. Apparently reading the port sends a detectable pulse to the controller and Batsly A had rigged up some Arduino stuff to read this - the other end was spliced to a LSDJ sync cable and thus LSDJ was slaved to the NTRQ pulse. It wasn't working totally correct though and would drift out of sync after a while.
We never continued with it though - both got side-tracked I imagine
would it be difficult to make an nes rom that ONLY sent out clock pulses through the player 2 port? if that existed, then someone could give the arduino end of it a try. and if they got that working, then the nes rom could have features added to it (like maybe the ability to play back an nsf file).
TouchOSC (which as the name says uses OSC not midi) is an interesting option, though I've heard many reports of it not being very reliable in a live situation. Right now the only means of sending and receiving data from the ipad is through Wi-Fi, and that's apparently where the problem lies. Before you start selling stuff you might want to test the ipad solution... it might not be as cool as it looks... On the other hand... controlling old school chips with an ipad is a bit of an oxymoron, don't you think so?
i've heard that different programs have varying degrees of latency. it was more of a problem on the iphone though. the ipad is faster so there's less latency.
this isn't an idea for visuals, but i just wanted to say that i think it would be incredible if there was a way to sync up an NSF file on a powerpak with a gameboy playing LSDJ.
In the experiments we did with NTRQ, it was only really possibly to have the NES as the sync master and LSDJ as the slave (sync pulse only comes *out* of the NES as opposed to going into it). Could be possible though, with those restrictions in mind.
i would be incredibly happy working within those restrictions.

has anyone here ever used an ipad as a midi controller? i know there are several apps out there that do this.
i'm considering selling off a large portion of my midi controllers and buying one of these. i have so many that i'm just never going to use. they sit in boxes in my closet, collecting dust. if i could sell them off and buy one of these things, i feel like that'd be a great trade.
but i'm not going to do that until i do my research.
