Yes I saw that thread (but only yesterday since I check this forum quite infrequently these days, maybe only once in a couple of months) and was sorry that I could not think of any way to help with that. I would agree that the problem might be with the main PCB since you also said that no sound is heard. To add some ramblings on Fusion architecture, it is interesting to note from the schematics that it seems that the Fusion may have been intended to be also made as a cheaper version that would lack the second voice engine and hard disk (and therefore also the 8-input HD recording feature). This is evident by these features being in the separate "Digital Expansion" PCB and more so by there being configuration jumpers (actually resistor placements) in the main PCB to be one of: S60, S60HD, S80 or S80HD.

The Akai MPC 5000 uses a lot of the Fusion's Technology and it only has one voice engine (which is probably why some of these parts are still available for the Fusion) e.g. LCD display, PSU, Inverter PCB, Dimmer PCB, E3 memory modules, etc.

EDIT: Okay, there was some confusion here about removing some posts and moving this thread. This post's text now reposted further below.

I am trying to Re-Strucure/Organise the Forum - it takes a lot of time. pev69, I put your block diagraham in a PDF on 11x17 inch page. I love it. I will be printing it out for my music room and to use as a reference. I wish we could get Mastropiero to continue working on his project www.promusicproducts.com/forum/phpBB2/viewtopic.php?f=2&t=5565Attachments:

I'm glad you like it! You (or any of you reading this ) can use the block diagram any way you like. I could also provide one with more resolution or even the original Visio document (.vsd), just ask. I did not know about Mastropiero's project. Looks good.

A link to more IDE/PATA SSD drives linkThey have both 2.5 & 3.5 inch IDE/PATA drives - They have a 30 day return policy Note the 2.5" drives are true IDE/PATA drives
The 3.5" drives are SATA drives with an IDE/PATA to SATA converter cable, but they have these in SATA II 3GB format, which may be a usable drive in the Fusion if anyone wants to invest some time and money to check them out.
SATA III definitely will not work in the Fusion - I have connected both SATA II & SATA III drives to Fusions eSATA port, neither show up in a normal boot up of the Fusion, but the SATA II drive did show up in the Fusion Diagnostic mode with faster access times than the internal IDE/PATA drive .The Alesis Fusions IDE-PATA and eSATA Ports.pdf (692.24 KB)

Unfortunately the IDE to SATA adapter did not work with the SATA II SSD nor did the IDE to CF card reader, they do work when connected to a computer, but not with the Alesis Fusion. Due to the lack of support for needed Firmware/OS programing we appear to be limited to IDE/PATA storage drives. If you want an SSD drive for your Fusion get a PATA/IDE SSD while they are available View Attachment

I connected a 40 pin 80 wire dual drive IDE cable to the Fusion IDE hard drive connection in an attempt to see if we could have a MASTER and Slave drive, but it would only recognize the Master drive. Fusion load times My Working Fusion - Open Fusion - PSU(old version)Primary Heat Sink Temp(the short one) It seems that the heat produced by the old version PSU varies - my non working Fusion PSU had a peak temp of 131 and my working Fusion PSU had a peak temp 123.3. Note: Temperatures shown below are the Peak Temperatures observed. The Heat Sink Temperatures cycled between 118.7°F and 123.3°F with no activity on the Fusion, The Fusion was simply Idle. No great temperature change on the Primary heat sink no matter which HD was installed. HD Storage Device Primary Heat Sink Peak Temp Measured Maxtor 40GB IDE/PATA HD 123.3°F Kingspec 64GB PATA SSD 123.3°F WD 160GB IDE/PATA HD 122.5°F Go with the PATA/IDE SSD drive if you want to eliminate the noise from the hard drive and a more a reliable drive for gigging. The PATA/IDE SSD drive itself probably runs cooler than a regular hard drive, but does not appear to lower the PSU temperature. I am not gigging with my Fusion, it remains in my music room and the small amount of noise from the WD 1600SB 160GB drive is not an issue to me. The WD 1600SB 160GB drive drive has the fastest load and transfer rates of the (3) drives I tested so for me, this is the drive I will use in my Fusion. I will keep my 64GB Kingspec PATA/IDE SSD drive and the original Maxtor 40GB as backup drives if needed.

This is an old thread, but just thought I'd post in case anybody still looks here, I've posted the same info at the www.alesismusic.com group. Having finally found a usable older Fusion 8HD and studying the huge ampount of info from users here an elsewhere-purchased a "DCP" brand (Our Drives Work) on ebay 128GB PATA?IDE SSD to find it doesn't work with the Fusion but fine w/computer. The reason-it is actually internally a mSATA drive-is not a true IDE even though the pin configuration is the right 44-pin same as my laptop 2.5" IDE wich I had a spare-and it is now installed in the Fusion and works perfectly. Stick with the Kingspec, which I should have followed parametric's knowledge and stuck with that. As far as the SATA port in the back-I recall that in earlier versions of Windows-the bios needed an update to work with SSD drives if you were using an adapter to convert from the older 44-pin interface to the newer SSD for a laptop. And-you also needed this bios upgrade if you already had an SSD drive and interface stock factory installed-but were installing an older version of Windows. From my experience with Microsoft OS from DOS to windows 10-apparently only Windows 7 was ready for the SSD drives-and even then you might still need the update for the bios depending on your computer-this may have something to do with why this Fusion ouboard SSD connector doesn't seem to function. If the instructions/drivers aren't in the firmware, we are kind of sunk. I'm also going to try this-if i can figure out how-reverse engineer the SATA port to an IDE port/adapter-connect an IDE hard drive and see what happens. May sound crazy, but who knows, maybe it will work. would be nice to have any kind of outboard drive but with the Cf card interface, kind of redundant although even the PIO mode for hard drives in our Fusions is faster than the CF card interface-I think at least it is on computers generally.But then, I am using stats I measure with the USB 2.0 ports on my laptops which slows down fast CF cards too. Anybody able to check the CF card throughput on the Fusion CF card port? I think I recall one stat-is only 1.8MB per second for transfer from the Fusion USB port to the computer. don't know about the card port. And using a CF card with an adapter as the main drive in a Fusion-not a good idea-will probably work-but the speeds/throughput-not sure but i think it would be slower than the internal IDE hard drives stock. I've converted several digital recorders from hard drives to CF card adapters-but with no appreciable difference in throughput-even with a digital recording deck-unless I use a very fast CF card-it is actually slower than any of the IDE hard drives I've replaced.
