I do not know what SSL does on Channel 2 and 4 with VSwDir set upwards. I need someone to verify the following information for me since I cannot find it myself: If you are using one instrument track with several channels, be very careful. However, you must take care to treat each channel as monophonic and ensure a channel is playing only a single sound at a time. If you do not use several instrument tracks for each channel but just one per, and want to modify the sound part of the way through, you may have to use automation on the knobs. It can be messy, as such, to have several channels enabled on one instrument. You can use several if you WANT, but if you want to stay true to the original you must use only one Channel-1 instrument at a time, only one channel-2 instrument at a time, etc. If one can modify the parameters partway through (see bold point of Disclaimer for explanation of conditional): Each channel can only play one note at a time. This means you have four Freeboy instruments on your Song Editor. Now, in the original gameboy, all these four channels were capable of playing at once, but each channel could only produce one sound at a time. It seems 7 gives a more regular-sounding noise, 15 gives a more irregular noise. I have no idea what Shift Register Width (SRW) does. On downward, the lower the value the faster the fadeout. SSL seems to work the same as it does on Channel 2: Control volume. It is located visually on the left of Channel 2 and above channel 3.] Located below Channel 2 and Channel four visually.įreeboy1- Wave.png (134.48 KiB) Viewed 4865 times It modifies the oscillator wave only, it does not impart an LFO. However, setting this to 0 means the note never fades out or stops unless the key is released. Again, I can't hear a difference in upward mode. The SSL volume controls the length of each step in volume shift. Here, the sweeps are volume sweeps, whereas in channel one they are pitch sweeps. Sweep time is the amount of time taken to complete the (pitch) sweep (ie, all the pitch steps) and end up at last pitch step. While, when sweeping pitch downward, it'll continue forever (I didn't hold more than a minute, but probably continues forever) or fade out (based on direction of volume sweep), in upward pitch sweep, it ends abruptly. Upon sweeping upward, it controls number of pitch steps, but upward pitch steps appear to be lesser in number. Sweep RtShift amount (SRS) seems to control number of pitch steps before reaching and staying at baseline frequency. This is why 1 and 3 sound the same, as they are phase inverted. (It is possible this is in n:4, where n is whatever the value is. (Presumably this is what "2" means, as in 1:2. It here is called wave pattern duty (WPD).Ī perfect square wave has 50% as the max and min occupy equal amounts. The ratio of the length of max to the total wavelength is called wave duty cycle. I can't hear this one clearly, and my ears have been acting up these past few weeks.Ī square wave may have a wave shape like this.įreeboy2- Rectangular wave.png (51.03 KiB) Viewed 4865 times If sweeping upward there seems to be very little difference. Other than 0, the lower you go, the more staccato it sounds. It essentially controls the length of each note as the pitch sweeps downwards. Has volume control, and a knob for "length in each step in shift" (SSL). The VSwDir, volume sweep direction arrow, controls direction of volume sweep: Upward means the note sound doesn't stop on its own (unless SwDir is also up, in which case it stops beyond a point), whereas downward means the note starts high and fades out. The sweep direction arrow (SwDir) controls whether pitch sweeps upwards or downwards. This acts like a high-shelf and low-shelf. The freeboy lets you control, master, left volume and right volume, treble volume and bass volume. The freeboy lets you choose a stereo option: Hard left, hard right, or centre, per channel. Channel 1 and 2 are square/pulse channels. I also want to ask the LMMS documentation team for writing documentation for nesclaine, freebody and SID with similar content as above. Is there somebody interested in writing chiptune tutorials for nescaline, freeboy and SID with specific focus on the different channels and a summary of what each button of the instrument is doing exactly? Maybe with example (small) songs for LMMS that we can download. Without documentation, I can't figure it out. What number of channels did the original hardware have and how are they mapped to the instrument channels? What are the buttons doing, what channel represents a specific channel on the NES. There seems to be no documentation for nescaline, freeboy and SID which makes it very difficult for beginners. As you can read here I try to make a NES chiptune.
