Logic Pro 9 Manual

[Leto Corrales]

WhenI add it, save and preview form, it works exactly as intended and fine. But later, if I refresh the website, or if I open again the Settings of the question where the skip logic lies, the skip logic code is gone, it just shows the empty code box. And of course, the skip logic no longer works.

Hi @rvilla, it looks like you are potentially applying skip logic that references the same question? (question name of installations_Coverage and then skip logic referring to $installations_Coverage on that question)

Is this the case?

Please forgive the basic nature of this question, but is there a manual for Alchemy? My usual method of just twisting knobs and seeing what happens is not yielding the results i need, but I'm sure Alchemy is capable of it. I've gone into the advanced page, but I must be overlooking some switch that makes different parameters, etc., active, because i move things around and nothing happens. Thanks.

Thanks for the reply. I followed the link and did some reading, but I'm obviously missing some key step. In the attached screenshot, I took a 4-beat sequence, which looks to be divided into 16th notes. Nothing i do in the window which shows the sequencer produces any changes. As a test, I was just trying to progressively lower the level of each 16th note, but there is no change; all the 16th notes play at the same volume. I imagine there must be a way to make changes in the sequencer window active, but i can't seem to do it.

Questions: when you say you "I took a 4-beat sequence, which looks to be divided into 16th notes", does that mean this was a preset, or did you load a sample into it? If it was a preset, what was the original called?

In that patch above (checked in my library version), Alchemy is playing a drum loop sample, and the Sequencer modulator by default is not routed to anything, so any changes you make to the sequencer will have no audible effect, as it's not modulating anything! (Show Target doesn't show the Sequencer modulator at all.)

Thank you both. I think I'm tantalizingly close... I added the modulation as Erik showed. I made the attached screenshot. I would think that, the way I have it, I would only hear sound at the downbeat, and then at steps 4 and 9, but the entire 1-bar loop plays at full volume. I'm used to working with audio samplers, so I ended up bouncing the sequence and then cutting it up with flex time and manipulating it, but I imagine there's a more direct way to do it. I appreciate your patience.

You have zero modulation depth, so in effect you are modulating the volume by nothing, so there will be no change from the modulator. Increase (you can also decrease, it's bipolar) the mod depth - the "Depth" knob to the right of the Sequencer modulation source.

des99, Thank you. I got the volume to work by playing with the depth, as you pointed out. I promise this will be my last question for today: I threw caution to the wind and tried to do the same with the swing function. So far, I have had no success. I attached a couple of screenshots; the only difference is having the edit mode in the pull-down to the left of the sequence showing either "value" or "swing", with the swing turned up to 70% and the mod depth up all the way. I put all the bars in the sequence up as far as they would go, as i want maximum swing on each beat There is no audible difference.

I think the slight stumbling block you may be having is you are building a (flawed) model of how you *think* it works, then finding it frustrating because the software's behaviour isn't matching that.

The sequencer isn't playing the beats. "Swinging" the sequencer won't swing the beats, which is what I think you are expecting, from what you write above (perhaps I'm wrong about that?). The term "sequencer" is, I think, misleading you.

The sequencer is a "Step Sequencer", like they have in modular systems, not a sequencer like a MIDI sequencer. It's simply a series of rhythmic modulation stages which you can route to various synth parameters. If you have a single raw synth waveform playing, and you route the step sequencer to the filter, and change the step heights (which is the depth of modulation for each step in time), the filter will "burble" in sync.

In this patches' case, we are simply playing a drum loop sample. The "beats" in the sample bear no relation with the step sequencer, except in terms of a coincidence of timing, as everything is synced to the same time/beat reference (Logic's tempo). The step sequencer is simply a modulation source ticking along in time with the sample playback.

Now, we've routed the step sequencer to modulate the source volume, so we can raise or lower the volume of that source any given 16th beat in the bar - the height of the step dictates the amount of volume modulation for each step.

Now, when we "swing" the steps, what's happening is the step modulator's timing gets swung, so now some of those steps will be shifted later in time. This means now that the steps in the sequencer won't line up exactly with the beats in the sample - because those are straight 16ths. When you'll hear is that as you turn up the swing, the swung beats will start "missing" some of the straight 16th transients in the sample. (Eg, step 3 won't trigger until just *after* the transient of 3/16th, rather than coincidence with it as when the step modulator was unswung.

If the drum loop is confusing you, try it on a straight simple, non beat sample, like a straight waveform. The timing of the sequencer steps will be more obvious as it's not super-imposed on a straight 16th rhythmic sample.

That definitely explains it. This is a more sophisticated form of modulation automation than I'm used to and you're right, I was trying to make it do something it's not designed to do. As I wrote earlier, I ended up converting it to audio to get what I want and now I won't waste any more time trying to make it do something it can't. Thanks again.

After 2 seconds of inactivity, manual watering will begin and sequence through each valve of the entire program. Once manual watering has been completed, the controller will automatically return to the automatic mode with no change in the previously set program.

I'm looking for a resource that can tell me exactly what each of the blocks in the Micom PSL logic do. I've read the manual for the relay and used the help file but the descriptions in these areas are so vague it leaves me with more questions than answers.

The risk-limiting audit is a procedure that provides strong statistical evidence that the election outcome is correct, or has a high probability of correcting an outcome that wouldn't match a full hand count of the ballots. The audit itself requires human beings to examine and verify more ballots in close contests and fewer ballots in contests with wider margins.

The 1% Manual Tally is required to be performed after every election. The 1% Manual Tally is a subset of ballots, representing one percent of precincts chosen at random, will be manually tallied and compared to the software-counted votes to verify they match.

The power provided to USB devices that are connected to Host connector J2 is not regulated. Therefore it is necessary to limit the maximum voltage of an external battery pack to 5.5V DC. The minimum voltage of the battery pack depends on the application -if the USB Host function (J2) is used, at least 4.6V needs to be provided. In other cases the minimum voltage is 3.6V.

The voltage regulator chosen for the power supply on the Basys 3 is the LTC3663 for the main board power and was chosen to create the required 3.3, 1.8V and 1.0V supplies from the main 5V power input). The auxiliary and RAM functions of the FPGA use the LTC3621 chip. Referring to the below table provides additional information as to the typical currents and values that are needed. However, keep in mind that this has largely to do with FPGA configuration and the values that are provided are given with parameters of a medium sized or speed design.

After being reset, the FPGA will immediately attempt to reprogram itself from whatever method has been selected by the programming mode jumper.The following sections provide greater detail about programming the Basys 3 using the different methods available.

The Xilinx tools typically communicate with FPGAs using the Test Access Port and Boundary-Scan Architecture, commonly referred to as JTAG. During JTAG programming, a .bit file is transferred from the PC to the FPGA using the onboard Digilent USB-JTAG circuitry (port J4) or an external JTAG programmer, such as the Digilent JTAG-HS2, attached to port J5 (located below port JA on the underside of the board). You can perform JTAG programming any time after the Basys 3 has been powered on, regardless of what the mode jumper (JP1) is set to. If the FPGA is already configured, then the existing configuration is overwritten with the bitstream being transmitted over JTAG. Setting the mode jumper to the JTAG setting (seen in Fig 3) is useful to prevent the FPGA from being configured from any other bitstream source until a JTAG programming occurs.Programming the Basys 3 with an uncompressed bitstream using the on-board USB_JTAG circuitry usually takes around five seconds. JTAG programming can be done using the hardware server in Vivado. The demonstration project available at digilentinc.com provides an in-depth tutorial on how to program your board.

When the FPGA has been successfully configured, the behavior of the LED is application-specific. For example, if a USB keyboard is plugged in, a rapid blink will signal the receipt of an HID input report from the keyboard.

The Basys 3 board contains a 32Mbit non-volatile serial Flash device, which is attached to the Artix 7 FPGA using a dedicated quad-mode (x4) SPI bus. The connections and pin assignments between the FPGA and the serial flash device are shown the below figure.

FPGA configuration files can be written to the Quad SPI Flash, and mode settings are available to cause the FPGA to automatically read a configuration from this device at power on. An Artix-7 35T configuration file requires just over two Mbytes of memory, leaving approximately 48% of the flash device available for user data.
